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.

Why Kate loves this

In love with the Mia Plunge's flattering silhouette, with its deep V cut and wide shoulder straps to give a natural lift. We made it from eco-friendly milk silk and an OEKO-TEX certified cotton blend, so it feels ultra-smooth against the skin. Plus, it’s been tested for color run and durability in the wash, which means you can wear it on repeat without any worries. Perfect for those days when you just want something effortless and comfortable!

Proudly made from a sustainable milk silk
and an OEKO-TEX certified cotton blend.
Silicone-free.
Style has overall minimal exposed seams with the exception of serged overlocking seams at the base of the cups.
Non-wired padded bralette with convertible adjustable straps and removable padding.
Cups have some base ruching to cater for the curvature of our boob shape.
Comes with a hook and eye closure with elastic band.
No colour run after a 24 hour soak test.
Machine-washed without a lingerie bag with no shrinking, piling and minimal wrinkling. We always recommend hand-washing or putting your intimates into a lingerie bag though!

If you have to machine wash, these are our recommended machine settings: Delicate setting, spin at 400RPM, at temperature of 30 degrees celsius. This helps to prolong the lifespan of the elastic bands and straps.
Do not soak or machine-wash in hot water.

Produced at OEKO-TEX® STANDARD 100 certified workshops.
Small batch production to minimise waste.
With the exception of Friday, Saturday and Sundays, we aim
to deliver your package within the next business day. As soon as your package has left our warehouse, you will receive a confirmation by email.
