Why Finding Your Size Across Brands Is Challenging
Not all bra brands carry all sizes. In fact, most mainstream brands only cover a fraction of the bra sizes that actually exist. This is frustrating if you wear a size outside the "matrix" — the limited range of 32-38 A-DD that dominates department stores and mall retailers. If your size is a 28DD, 30G, 40H, or 44C, you have likely struggled to find bras that fit both your band and cup.
The problem is rooted in manufacturing economics. Mass-market brands optimize for the most common sizes to maximize inventory turnover. But sizing surveys, including data from A Bra That Fits, consistently show that properly measured bra sizes are far more diverse than what stores stock. An estimated 30-40% of women wear band sizes 28-30 or 40+, and cup sizes regularly extend to UK H-J cups and beyond.
This tool scans our database of 70+ lingerie brands to tell you exactly which ones carry your specific size. Enter your size above to see your options — including direct shopping links, the sizing system each brand uses, and the sister sizes you can also try in that brand.
Why Finding Your Size Can Be Difficult
Many people wear sizes that fall outside the "matrix sizes" (32-38 band, A-DD cup) that most mainstream retailers stock. If you wear a small band with a larger cup (like 28DD or 30G), a plus-size band (42+), or extended cup sizes (G+), you may have experienced the frustration of never finding your size in stores.
The good news is that specialty brands and online retailers now offer a much wider range of sizes than ever before. Our database includes over 70 brands with their full size ranges to help you find exactly where to shop.

International Size Conversion When Shopping by Brand
When a brand uses a different sizing system, you need to convert your size before checking availability. For example, if you wear a US 34G, your UK size would be 34F. So when you check if a UK brand like Panache carries your size, the tool converts automatically and shows you the UK equivalent.
Similarly, EU sizing uses centimeters for the band and different cup progressions. A US 34DD roughly corresponds to an EU 75E. Japanese sizes run smaller — a US 34C is approximately a JP 75D. Our tool handles these conversions automatically, so you can confidently shop international brands without manual calculation.

How to Verify a Brand Carries Your Size
Even when a brand technically lists your size, not all sizes are always in stock. Before getting your hopes up, here is what to check:
- Check the brand's official size chart. Some brands list a wide range on their marketing pages but actually only produce a subset. The official size chart tells you what they truly manufacture.
- Read customer reviews. Reviews often reveal if a brand's sizing runs differently than advertised — particularly for cup depth and band stretchiness. Pay attention to reviews from customers with a similar size to yours.
- Check the return policy. When trying a new brand, make sure they offer free returns or exchanges. Sizing can be inconsistent, and you don't want to be stuck with a bra that doesn't fit. Look for at least 30-day return windows.
- Look for size-specific filters. Sites like Bare Necessities, HerRoom, and Bravissimo let you filter by exact band and cup size, which is much faster than checking each product page individually.
