Womens Bra/Bralette Size GuideUpdated 11 hours ago

Getting the right fit in your bra or bralette starts with your underbust. We recommend using your underbust measurement as your main guide when choosing a size — it’s what helps keep your bra secure and supported. Then, check your bust measurement to ensure the right amount of coverage and comfort.

How to measure:

  • Underbust: Measure directly under your bust, where your bra band would sit. Keep the measuring tape snug and level around your torso.

  • Bust: Measure around the fullest part of your bust, ensuring the tape is straight across your back and not pulled too tight.

In between sizes?
If you’re between sizes, we suggest choosing the size that matches your underbust to ensure your bra stays in place and feels supportive.

If there’s a noticeable difference between your bust and underbust — for example, your underbust suggests a Small but your bust measures more like a Large — we recommend choosing the Medium. It’s the best middle ground for security and comfort.

Our bras and bralettes are made with soft, stretchy fabrics that mould to your shape, offering comfort without compromising on style. Bralettes offer minimal support and coverage, while our bras are made to provide more structure and hold.
