Quick Fit Notes
- All bras are wire-free in natural fabrics for breathable comfort.
- Band sizes for many of our styles are XS–2XL (≈ AU 8–18). If you’re on the top end of a range or prefer less compression, size up.
- Petite/Full/Extra Full indicate cup capacity. Petite best for A–C; Full for C–E; Extra Full for F & G (varies by style).
- Underwear: waistbands stretch over the widest part of your hips and sit softly at the low hips (low rise), mid-hip (mid-rise), or high hips (high waisted).
- Ruffle Knickers: as our fabrics are light, the ruffle edges do flatten but they are not invisible under fitted clothing. We designed the Martina style to give this option, as its elastic finishing sits flatter under clothing.
How To Measure
Use a soft tape, stand naturally, and keep the tape level around your body. Wear a supportive bra if you have one, as this helps get the most accurate cup size. Use your true measurements — you can always size up if you prefer a less firm fit in underwear.
- Underbust: snug around ribcage under the bust — this sets your band size.
- Bust: around the fullest part of your bust (not too tight).
- High Hip: where mid-rise underwear sits (about 5 cm below belly button).
- Low Hip (widest part): the fullest point across your bum/hips.
