Find Your Style by Cup Type

A / B Cup

Lighter and more delicate in shape. Bralettes, soft-cup styles, and lace designs work beautifully. Look for styles with minimal padding that celebrate your natural silhouette.

C Cup

A versatile size that suits most styles. Underwire and soft-cup options both work well. Try structured lace or light padding for an elegant, supported look.

D Cup

Prioritise support without sacrificing beauty. Look for wider straps, full-cup designs, and reinforced underwire. Our luxury and lace collections offer excellent options at this size.

E / F Cup

Full-coverage styles with firm underwire and side support panels provide the best fit. Choose wider bands for all-day comfort. Japanese sizing tends to run true-to-fit at larger cups.

Fitting Tips

📏

Measure on a bra-free day

For the most accurate measurement, measure without a bra or while wearing a non-padded bralette. Padding adds volume and can affect your band and cup reading.

🪡

Keep the tape parallel

When measuring your bust, ensure the tape is level all the way around — not dipping at the back. Even a small angle can change your cup size reading by one full size.

Start on the loosest hook

A new bra should fit comfortably on the loosest hook. As the fabric stretches over time, you can tighten the band — giving your bra a longer, better-fitting life.

Common Fitting Problems

This usually means your cup size is too small. When the cup is too shallow, the underwire sits on breast tissue instead of the rib cage. Try going up one cup size — for example, from B to C — while keeping the same band size.
Falling straps are almost always a band size problem, not a strap problem. If the band is too loose, it rides up at the back and pulls the straps forward. Try going down one band size — for example, from 75 to 70 — and adjusting the straps only after the band fits correctly.
A gap at the top of the cup means the cup is too large. Try going down one cup size. If the gap only appears in certain positions, your cup shape may not match your breast shape — fuller-coverage styles often solve this.
Go up one band size. Keep in mind that a slightly larger band may require you to go down one cup size to maintain the same cup volume — for example, 75C and 80B offer similar cup volume with different band fits.
Japanese bra sizing uses the same band numbers but tends to run slightly more fitted than European or American sizing. If you normally wear a European 75B, you may find a Japanese 75B fits more snugly. When in doubt, go up one band size or use the chart above to remeasure from scratch.
