Introduction
Plus size women’s clothing in the UK has undergone a significant transformation. The UK average dress size is a 16, which means what the fashion industry calls plus size is actually the most common body type in the country. Brands have slowly recognised this, driven partly by social media giving plus size women a platform to demand better and partly by the simple commercial reality that ignoring half the population is poor business.
The result is more choice, better quality, and increasingly, the same designs available in standard and extended size ranges rather than separate, limited collections. However, the landscape is also shifting in complex ways. Recent analysis has found that some high street retailers are scaling back their plus size ranges amid surging use of weight loss medications, raising concerns about inclusivity.
This guide covers everything you need to know about plus size women’s clothing in the UK in 2026. From the best retailers and their size ranges to styling tips, fit advice, and the trends shaping curvy fashion, it is a comprehensive resource for finding clothes that fit, flatter, and feel good.
What Counts as Plus Size in UK Fashion?
In UK fashion, plus size generally refers to UK sizes 16 and above, though many brands now extend their standard sizing through to UK 22 to 26 as a matter of course. The definition is not fixed. Some retailers categorise plus size as starting at size 18, while others begin at size 16 or even 14.
What matters more than the label is whether the garment has been designed for curves. Many brands simply scale up a size 10 pattern, which results in poor fit through the bust, waist, and hips. The best plus size clothing comes from brands that design specifically for larger bodies, fitting garments on actual plus size figures rather than grading up from a smaller sample size.
Sizing varies significantly between brands, countries, and manufacturers. A size 18 in one brand can differ by several inches from a size 18 in another. Always check the specific brand’s size chart and read customer reviews for fit advice rather than assuming your usual size will translate across retailers.
The UK Plus Size Fashion Landscape in 2026
Retailers Scaling Back Plus Size Ranges
Recent analysis by retail intelligence platform Edited has found that several UK high street retailers are reducing their plus size offerings. At Marks & Spencer, the proportion of new dresses offered as size 18 and above fell from 34 per cent to 27 per cent. The very largest sizes, 22 to 24, accounted for only 0.4 per cent of dresses compared with 2.2 per cent two years ago.
At John Lewis, while the overall number of new plus size dresses increased, the largest sizes only accounted for 19.2 per cent of the range this summer, down from 22.3 per cent in 2024. Debenhams saw plus size dresses fall from 23 per cent to 17.4 per cent of those on sale.
This shift has been linked to the rising use of GLP-1 weight loss medications such as Mounjaro and Wegovy. An estimated 5 per cent of all adults in Britain, nearly three million people, are currently taking the injections, with analysts expecting usage to rise to about 13 per cent by the end of next year.
Concerns have been raised about the potential for larger people to be shut out of high street fashion. Fashion influencer Caroline Sigamoney criticised a lack of inclusive sizing at M&S, stating: “This is exactly why so many plus-size women have given up shopping on the high street.”
The Return of Evans
In a counterpoint to the scaling back trend, plus size womenswear brand Evans returned to the high street in 2026. The brand, which caters to sizes 14 to 32, closed all stores and concessions in December 2020 after its parent company Arcadia Group fell into administration.
Evans is now available in over 50 Yours Clothing stores across the UK and Ireland, offering a curated collection of dresses, tops, trousers, and occasionwear. The brand was founded in 1930 and has been a cornerstone of British plus size retail for decades.
Best Plus Size Retailers and Brands in the UK
Yours Clothing
Yours Clothing is the UK’s leading plus size womenswear retailer, offering trend-led fashion in sizes 14 to 40. It is one of the most size-inclusive brands on the high street, scoring 9.43 out of 10 in a study of UK fashion brands, with a measurement range of 30 inches between the smallest and largest sizes.
The brand designs garments on actual plus size bodies rather than grading up from a sample size. Its in-house team fits every garment on real plus size figures, which results in better cut, grading, and proportions for curves.
Yours Clothing also offers:
- Footwear: UK sizes 3 to 13 in regular, wide, and extra-wide (EEE) fits
- Lingerie: Extended band and cup sizing up to 50H
- Sub-brands: Limited Collection, Yours London (occasionwear), and Bump It Up Maternity
The sizing system has a quirk: many pieces are graded to fit two sizes at once (14/16, 18/20, and so on). If you sit at the smaller number of your pair, you may want to size down rather than up.
Simply Be
Simply Be is a UK-based retailer carrying sizes 10 to 32 across its own label and brands like Joe Browns, Joanna Hope, and Chi Chi London. The core range runs from UK 10 to UK 32, though the real sweet spot where the most styles live is 14 to 28.
Simply Be sizes run generously, typically a half to a full size larger than the label suggests. The sizing philosophy is rooted in curve-fit, meaning more room through the hips and thighs and a longer back rise in trousers. This is particularly beneficial for curvy and pear-shaped bodies.
The brand offers denim, lingerie, formalwear, and trend pieces, with a Shape Sorter feature that helps filter styles by body shape.
ASOS Curve
ASOS Curve offers one of the widest plus size selections online, from sizes 18 to 30 across casual, workwear, and occasion categories. The range is trend-led and affordable, with new styles added weekly. Returns are free, which is important when shopping online for fit.
The London-based design team creates new shapes and fits specifically for UK sizes 18 to 30, covering denim, occasionwear, and jumpsuits.
New Look Curves
New Look has quietly built one of the best plus size high street ranges in the UK. Prices are accessible, the style is current without being too trend-driven, and the fit is designed for curves rather than simply sized up from smaller patterns.
New Look Curves sizing runs from UK 18 to 32, with size conversions of S (18-20), M (22-24), L (26-28), and XL (30-32). The range includes jeans, skirts, dresses, and denim.
River Island Plus
River Island Plus extends the brand’s core offerings into extended sizes, focusing on dresses, tops, denim, outerwear, and accessories for sizes typically 18 to 28. The collection is designed to fit UK sizes 18 to 28, with the strongest denim selection in the affordable plus size space.
M&S
Marks and Spencer carries most of its range up to size 24 and selected items to size 28. The quality of fabrics and construction is typically higher than fast fashion alternatives, making M&S particularly good for workwear and basics that see heavy rotation.
However, as noted earlier, the proportion of larger sizes has decreased in recent seasons.
Roman Curve
Roman offers a dedicated Curve range with flattering women’s plus size clothing ranging from easy breezy summer clothes to cosy winter options. The collection includes plus size dresses, partywear, and everyday essentials in sizes up to 30-32.
Scarlett & Jo
Scarlett & Jo is a UK-based brand specialising in plus size occasionwear. The Isabelle maxi dress, for example, is available in UK sizes 12 to 32 and features the brand’s POWERFIT soft stretch mesh, MagicBand waistband, and Advanced Fit Technology. The brand designs for comfort, movement, and shape, with styles suitable for weddings, race days, and formal events.

Plus Size Fashion Trends for 2026
Bold Florals and Prints
According to Who What Wear UK, key plus size fashion trends for summer 2026 include bold floral prints, rich jewel tones, retro-inspired wrap dresses, and statement maxi skirts. The movement away from muted, body-concealing styles toward bright, pattern-led fashion is one of the most positive developments in plus size fashion.
A common misconception is that smaller prints are more flattering. The opposite is often true: bold, larger-scale florals tend to look far more striking and intentional on a plus size frame than fussy small prints that can read as busy.
Wide-Leg Trousers
Wide-leg trousers have become something of a cult piece in plus size fashion for good reason. The generous leg creates a long, fluid line from waist to floor that is genuinely elongating and flattering on curves. The key is a high waist, which defines the smallest part of the torso, paired with a tucked-in top to keep proportions balanced.
The Barrel Trend
Barrel-leg silhouettes are having a major moment in 2026. With their relaxed fit through the leg and softly tapered ankle, barrel jeans and trousers offer a modern alternative to straight-leg and wide-leg styles. The shape creates volume through the leg without being oversized, making them a great option for those who want something roomier than skinny jeans but more structured than wide-leg styles.
For an everyday look, pair light blue crop barrel jeans with a white peplum t-shirt and ivory faux leather cut-out ballet pumps. The peplum shape helps define the waist, while the cropped length of the jeans showcases your footwear and keeps the outfit feeling balanced.
Co-Ord Sets
A well-fitting co-ord set is one of the most powerful pieces in the plus size wardrobe. When both pieces fit correctly, the matching proportion across the top and bottom creates a cohesive, polished silhouette that requires almost no styling input.
The Shift Dress
A shift dress, whether in a bold colour-block design or a simple solid colour, is one of the best garments for plus size summer dressing. It skims the body without clinging, works across a huge range of occasions, and requires almost no styling thought. Add block-heel sandals and simple jewellery for an immediately complete look.
Satin Fabrics and Corset Tops
Current night out trends include satin fabrics, corset style tops, wide-leg tailoring, matching co-ords, and statement accessories.
Statement Maxi Skirts
Flowing maxi skirts are a key trend for 2026, offering elegance and comfort in equal measure.
Styling Tips for Plus Size Women
Focus on Fit, Not Concealment
The idea that bigger bodies should hide under fabric is outdated. Clothes that follow your shape look better than those that obscure it. Structured fabrics and tailored pieces often flatter more than oversized, shapeless clothing.
Define the Waist
High-waist bottoms create definition. A high-waist trouser or skirt anchors any top and creates a clear waist. Belt your smocks and relaxed dresses to add shape.
Use V-Necks to Elongate
V-necks elongate the neckline and are consistently flattering across all body types and sizes.
Balance Proportions
When wearing voluminous bottoms like wide-leg or barrel trousers, balance the volume with a fitted or structured top. Conversely, pair a flowing blouse with straight-cut or wide-leg trousers and block-heel mules for a universally flattering silhouette.
Don’t Fear Print
The idea that plus size women should avoid print is outdated. Large florals, bold stripes, and abstract patterns look exceptional on fuller figures.
Tonal Dressing
Keeping similar tones throughout your outfit creates a streamlined look and allows the shape of the garment to take centre stage. Brown barrel-leg cropped jeans with a chocolate brown and cream boxy t-shirt and brown mule sandals is one example of how tonal dressing works.
Fit Tips for Plus Size Shopping
Check the size chart for every brand. Sizing varies wildly between brands. A size 18 in one brand can differ by several inches from a size 18 in another.
Buy based on measurements, not the number on the label. This saves time and returns.
Read reviews for fit advice. A review from someone with your body shape is worth ten size guides.
Use body shape filters. Tools like Simply Be’s Shape Sorter filter styles by body shape, which is particularly helpful for dresses and jeans.
Consider petite and tall options. If you are under 5’4″, petite ranges are worth checking. If you are over 5’8″, tall ranges offer better proportions in sleeves and length.
Size down for relaxed styles. Brands like Yours Clothing and Simply Be cut many styles generously. If you sit at the smaller number of a size pair, sizing down is often recommended.
Common Mistakes to Avoid
Mistake 1: Assuming Your Usual Size Will Fit
Simply Be fits a different shape to most high street brands, so your usual size 16 may feel like a roomy 18. Always check the specific size chart and read reviews.
Mistake 2: Buying Oversized Clothing to “Hide”
Clothes that follow your shape look better than those that obscure it. Structured fabrics and tailored pieces often flatter more than oversized, shapeless clothing.
Mistake 3: Avoiding Print
Bold, larger-scale prints tend to look more striking and intentional on a plus size frame than fussy small prints.
Mistake 4: Ignoring the Waist
High-waist bottoms and belted styles create definition and anchor any outfit. Without waist definition, relaxed styles can swamp the figure.
Mistake 5: Not Checking Reviews for Fit
Sizing inconsistency is a common issue. Reading reviews from customers with similar body shapes helps avoid disappointment.
Actionable Recommendations
- Start with the specialists. Yours Clothing and Simply Be design specifically for curves, with better fit through the bust, waist, and hips than scaled-up high street ranges.
- Try the barrel trend. Barrel-leg jeans and trousers offer a modern, flattering alternative to skinny and wide-leg styles.
- Invest in a co-ord set. A matching set creates a cohesive, polished silhouette with almost no styling effort.
- Define your waist. High-waist bottoms, belts, and wrap styles create definition and anchor any outfit.
- Don’t avoid colour or print. Bold florals, jewel tones, and statement patterns look exceptional on fuller figures.
- Check measurements, not labels. Buy based on your actual measurements against each brand’s size chart.
- Consider occasionwear specialists. Brands like Scarlett & Jo design specifically for plus size occasion dressing, with features like MagicBand waistbands and float sleeves for coverage.
