Plus size fashion is one of the fastest-growing segments in UK and US ecommerce, and the brands doing it well have worked out that inclusive sizing is not just a product decision: it is a store architecture decision. The best stores in this category handle size range communication, fit confidence, and representation on the product page in ways that directly affect conversion. Here are ten that have built their Shopify presence around getting those things right.

1. Navabi

Navabi is a UK and European plus size fashion marketplace that curates premium and contemporary labels, all in sizes 10 to 36. Their Shopify store uses a curation model to solve one of the core challenges in the category: helping shoppers find flattering fits across different brand sizing conventions. Product pages display size charts with both generic UK sizing and the individual brand's own measurements, which reduces the uncertainty that leads to high return rates. Fit notes on PDPs go beyond basic garment dimensions to describe silhouette, whether a style runs large, and what body type it suits.

Navigation is structured by occasion, body type, and trend, which mirrors how plus size customers actually browse: not just by product type, but by what works for their shape and lifestyle. That navigation logic reduces bounce from shoppers who arrive and cannot quickly find relevant products. Navabi also uses editorial content effectively, with style guides and outfit ideas that keep customers on site longer and provide natural links back into the product catalogue.

2. Yours Clothing

Yours Clothing is one of the UK's largest plus size fashion retailers and their Shopify Plus store handles an enormous product range without losing usability. The filtering system allows customers to narrow by size, occasion, colour, and fit type simultaneously, which is essential when you have thousands of SKUs. Product pages feature multiple model images across different sizes within the plus size range, which is a deliberate and effective response to the representation gap that still exists in mainstream fashion ecommerce.

Their loyalty programme, Yours Rewards, is integrated persistently across the site, with points earned shown on account pages and redemption options visible in the checkout. This kind of programme is particularly valuable in the plus size category, where customer lifetime value is high and brand loyalty is strong among shoppers who have found a retailer that works for them. Yours also runs persistent sales prominently, which drives urgency without undermining the brand by being perpetually promotional.

3. Simply Be

Simply Be is a long-established UK plus size and curve fashion brand, part of the N Brown Group, and their Shopify store is built around reducing the friction points specific to this category. Size confidence is addressed at multiple levels: detailed fit guides, model measurements shown on every PDP, and a customer review system that flags whether reviewers found the item true to size. The combination of those three data points gives a customer enough information to commit to a purchase without needing to order multiple sizes.

Their collection pages use trend-led editorial imagery alongside the product grid, which keeps the store feeling current rather than purely functional. Simply Be's paid instalment options (Klarna, Pay in 3) are surfaced clearly on PDPs and in the cart, which is a considered move given that their price points can reach into mid-range for occasionwear. The brand also uses email capture aggressively at entry, with a first-order discount, which feeds a lifecycle marketing programme built around new arrivals and size-specific styling content.

4. Eloquii

Eloquii is a US-based Shopify Plus retailer built exclusively for women in sizes 14 to 32. What stands out about their store is the quality of their product photography: models are shot in a range of sizes across the extended size scale, not just at one end of the range. That decision directly addresses the problem that even nominally inclusive brands often show plus size clothing only on a size 14 or 16 model, leaving customers at size 24 or 28 with no visual reference.

Their editorial voice is strong throughout the store: trend reports, styling content, and size-specific fit guides are embedded naturally into collection pages and the blog, which helps with both SEO and on-site engagement. Eloquii's collaboration drops and limited-edition collections are used to drive urgency and email list growth, with countdown timers and low-stock indicators on PDPs. The brand uses a consistent colour and print identity across collections, which makes their product grids visually coherent and easy to navigate.

5. Torrid

Torrid is one of the largest plus size fashion retailers in the United States and their Shopify Plus store is a case study in handling a very broad product range without overwhelming the customer. The homepage carousel features current campaigns prominently, while the navigation is structured to allow customers to find product by both category and occasion within a few clicks. Their "Hot Cash" promotional currency mechanic, displayed prominently in the site header during active periods, drives repeat visits during redemption windows and is one of the more sophisticated retention mechanics in the category.

Product pages on Torrid include customer photos submitted by real shoppers in specific sizes, which is a more credible form of social proof than filtered brand imagery. Size runs from 10 to 30 and the size selector on PDPs shows stock availability per size in real time, which prevents customers from spending time on a product page only to discover their size is unavailable. Their email capture offers direct size-based personalisation: customers indicate their size at sign-up and receive size-relevant new arrival emails, which lifts engagement rates significantly versus generic newsletters.

6. Universal Standard

Universal Standard is a New York-based DTC brand that runs sizes 00 to 40 at the same price point, which is their core commercial and brand proposition. Their Shopify store communicates this clearly from the homepage: no size-specific collections, no price differences, no separate "plus" section. That structural decision is itself a conversion message for a customer who has spent years navigating fashion retailers that charge more for larger sizes or relegate extended sizes to a separate, less well-stocked section.

Their "See It in Your Size" feature, which shows each product styled on models across the full size range, is technically well-executed and directly addresses the biggest product page friction point in inclusive fashion. Customers can filter model images by body shape or size, which turns a standard product gallery into a personalised fit tool. Universal Standard also offers a "Fit Liberty" programme: if you change size within a year of purchase, they send a replacement garment in your new size. That mechanic is strong on both conversion and brand loyalty, and it is surfaced effectively throughout the checkout journey.

7. Gwynnie Bee

Gwynnie Bee operates a rental subscription model for plus size fashion in the US, sizes 10 to 32, and their Shopify-based store is structured around the subscription mechanic rather than individual product sales. The homepage leads with the subscription proposition: how many items you can have out at once, the price per plan, and the mechanics of how returns and new selections work. That upfront clarity is essential for a subscription product, where confusion about the terms is the primary reason potential subscribers abandon the sign-up flow.

Their product catalogue doubles as a try-before-you-buy discovery engine: customers browse and add items to a queue, and Gwynnie Bee ships from the queue as previous rentals are returned. The product pages are structured to support this browsing behaviour, with quick-add-to-queue functionality and similar item recommendations. Gwynnie Bee also uses detailed occasion and event filtering, which makes sense for a rental model where customers are often looking for something specific rather than building a permanent wardrobe.

8. Soncy

Soncy is a US plus size fashion brand, sizes 12 to 30, with a strong social and influencer acquisition strategy that feeds into a Shopify store designed to convert first-time visitors efficiently. Their homepage is constructed to give a first-time visitor a clear brand impression within seconds: curated bestsellers, model imagery across the size range, and clear trust signals including returns policy and customer review counts. The store loads quickly and the layout is clean, which matters because their primary acquisition channel is paid social where landing page speed is a direct factor in conversion rate.

Product pages on Soncy use size-specific customer reviews prominently: the review system prompts customers to include their size, height, and whether the fit was as expected. That review format is more useful for a new customer than a star rating and a generic comment. Soncy also uses a points-based loyalty scheme that is visible in the account section and on PDPs, showing customers how many points a purchase will earn before they commit. That kind of pre-purchase points visibility is a simple but effective mechanism for nudging customers towards completing an order.

9. Addition Elle

Addition Elle is a Canadian plus size fashion brand, sizes 12 to 24, whose Shopify store serves both Canada and the US. Their store structure reflects a considered approach to brand positioning within the plus size category: the navigation includes a "Curvy Designers" section featuring collaborations with plus size advocates and designers, which differentiates their range and adds credibility to their inclusive positioning. Collaboration collections are featured with dedicated editorial pages explaining the designer's background and the inspiration behind the range, which gives customers a reason to engage with the content beyond the product grid.

Their product pages show fit notes written by buyers, not marketing copy, describing how a style fits through the waist, hips, and bust. That editorial specificity reduces returns and builds trust. Addition Elle's loyalty programme integrates with in-store and online purchases, which matters for a brand with physical locations in Canada, and the programme tiers are clearly communicated throughout the checkout and account section.

10. 11 Honoré

11 Honoré is a US luxury plus size fashion retailer, sizes 10 to 20W, stocking designer and high-end labels that are otherwise difficult to access in extended sizes. Their Shopify store is built to communicate luxury credibility first and foremost: the visual language, typography, and editorial photography are consistent with premium fashion retail, which matters in a category where plus size customers have historically been directed towards cheaper, less design-forward brands.

Their value proposition, stated clearly on the homepage, is that they partner with luxury designers to create plus size ranges that are designed specifically for the size, not just graded up from a straight-size pattern. That distinction is meaningful to their customer and it is communicated at every point in the browsing journey, including on PDPs where the made-for-size design process is explained. 11 Honoré uses editorial content to reinforce brand positioning: interviews with designers, trend reports, and event coverage that situate the brand within the broader luxury fashion conversation rather than treating it as a category aside.
