Most women know how important it is to wear the right bra size — but these days, you don’t need to trek to a fitting room every time you shop. Buying bras online is more convenient than ever, with many retailers offering a wider range of sizes and styles than the average high street store, along with easy sizing guides and hassle-free returns if something doesn’t fit perfectly.
To make your search easier, here’s our updated list of the best places to buy bras online in the UK. To make the cut, each store had to offer:
- A wide range of sizes and styles
- Free and easy returns and exchanges
- The ability to search by size and style
- Expert sizing and fitting advice
Bravissimo
Curvier women have been shopping at Bravissimo for years, and it remains the go-to retailer for larger cup sizes thanks to its exceptional range and customer service. You can search bras by size or browse by category — comfy bras, sleep bras, sports bras, stretch lace, and front-fastening styles among them. Bravissimo also sells swimwear, nightwear, sportswear, and clothing cut for fuller figures.
Rather than recommending a tape measure, Bravissimo offers a visual fitting guide to help you find the right size. Personal fitting advice is also available over the phone or via live chat, and students and NHS/emergency workers can save 10% with a valid card.
Bravissimo offers free 60-day returns for exchange or refund. Frequent shoppers can join the Bravellous Points reward scheme, earning one point for every full-price item bought — collect five points and you’ll receive a £10 voucher.
Size range: 28D – 40L bravissimo.com
Boux Avenue
Founded by entrepreneur and Dragons’ Den star Theo Paphitis, Boux Avenue has gone from strength to strength in recent years. In the year to March 2025, Boux Avenue delivered a major step forward in profitability, with sales growth of 6.9% — and momentum has continued into 2026. The brand now sells through its own website and stores, as well as through M&S, ASOS, Next, and Very.
Boux Avenue sells only its own brand, but the range is extensive — from everyday t-shirt bras and balconettes to strapless, push-up, and bridal styles, plus nightwear, swimwear, and activewear. A video fitting guide is available on the website, along with a live chat service for further advice.
Returns and exchanges are accepted within 28 days, and all returns are free within the UK.
Size range: 28A – 40G bouxavenue.com
Brastop
Brastop specialises in lingerie for fuller figures, stocking cups from D to K across a wide selection of styles from brands including Curvy Kate, Freya, Panache, and Pour Moi. As well as bras, there’s swimwear, sportswear, and nightwear in larger sizes.
You can shop by size or browse curated collections — whether you’re after everyday comfort, lace lingerie, or something to wear under a tricky neckline. Styles range from plunge and balcony to padded, sports, and underwired bras, as well as bralettes. The fitting section includes a video measuring guide, a visual fitting guide, and style-specific tips. If you’d like more tailored advice, you can book a virtual consultation with a bra fitting expert.
All bra orders are eligible for free UK and international returns within 90 days.
Size range: 28D – 44K brastop.com
Juste Moi
If you’re in the market for designer lingerie — whether as a treat for yourself or a considered gift — Juste Moi is worth bookmarking. With dozens of European luxury brands including Aubade, Empreinte, Katherine Hamilton, Lise Charmel, and Prima Donna, it carries styles you simply won’t find anywhere else on the UK high street or web.
The fitting advice includes a 5-minute guide based on your current bras, with additional style recommendations for your breast shape. Personal advice is available by phone or email. There’s also a thoughtful buying guide aimed at those shopping for a partner, covering both size and style.
Returns and exchanges are accepted within 28 days, though you’ll need to cover return postage yourself.
Size range: A – H cup justemoi.co.uk
Note: Figleaves, previously featured in this guide, closed its standalone website in 2021. The brand’s ranges can now be found on simplybe.co.uk.
