Tip: To get your overbust difference, follow this formula: overbust (cm) - underbust (cm). This gives you the cup size.

Tip: Full, Plus and Curvy sizing refer to the bra coverage in increasing sizes. For eg, S would fit a traditional A and B cup, Full would fit a C cup, Plus would fit a D cup and Curvy would fit a DD/E cup. Choosing the right one ensures the perfect fit and comfort!

As the Isabelle collection is crafted for a petite to regular fit, we are working on adapting this style to fit fuller busts!

Common Questions

While our base is predominantly in Asia, we’ve proudly served many beautiful European and Western ladies, and have fitted them well! Our sizing aims to be inclusive and adaptable regardless of nationality.

That said, many brands today offer larger stretch and cup coverage to simplify their size ranges and reduce stock, but this can sometimes compromise sizing accuracy. Because of this, we always recommend shopping based on your actual measurements for the best fit.

If you ever need guidance, our fit experts are here to help you find the perfect size for your unique shape, no matter where you’re from

We believe every body is unique, and traditional sizing labels like S, M, L or 32B, 34B, 36B don’t always capture the beautiful variety of shapes and proportions out there. That’s why we’ve designed our sizing system to be more inclusive and specific.

Our sizes still reference international sizing charts, so you’ll find familiar numbers and bands. However, our system lets you size up or down in cup coverage and band fit according to your personal preference and shape. This means you can choose a style that offers more coverage or a snugger band without compromising overall comfort or fit.

Let’s be honest—sizing charts can get confusing! You might be a 32G in one guide and a 34DD in another, which is super frustrating. We want to keep things simple and focused on what truly matters: how the lingerie feels on you.

Here’s how our sizing works:

Full, Plus, and Curvy refer to increasing cup sizes, similar to C, D, E cups.
S, M, L, XL, XXL, 3XL refer to increasing band sizes, similar to 32, 34, 36 bands.

If a size is listed as just S, M, L, or XL without Full, Plus, or Curvy, it means the fit is designed for A or B cup sizes. This keeps the fit comfortable and simple for smaller busts, while our Full, Plus, and Curvy options provide more coverage for larger cups.

By moving away from one-size-fits-all labels, we want to empower you to find lingerie that fits your body beautifully and comfortably. Our goal is to help you feel confident and supported, with styles thoughtfully designed for different body shapes — because fit isn’t just about size, it’s about comfort.
