Bold Bikini swimwear is cut to sit close and sculpt. Most styles run true to standard Australian sizing, with a supportive, flattering fit rather than a loose one. If you are between sizes, size up for fuller cheeky bottoms and size down for a snug triangle top.

How to measure
Bust: measure around the fullest part of your chest, keeping the tape level. Waist: measure the narrowest part of your natural waistline. Hips: measure around the fullest part of your hips and seat. Use a soft tape and don't pull it tight.
Fit by style
Triangle bikini tops are adjustable at the neck and back — choose your normal size for a secure, close fit. Cheeky and Brazilian bottoms give less rear coverage by design; size up if you prefer more coverage. One-piece swimsuits and maillots are cut for length through the torso — if you are taller than average or between sizes, size up for comfort through the body.
Frequently asked questions
How does Bold Bikini swimwear fit?
Bold Bikini fits true to standard AU sizing with a close, sculpting cut. Tops are adjustable; bottoms are designed to sit cheeky. If in doubt, follow your bust and hip measurements on the chart above.
What size bikini should I get if I'm between sizes?
Size up if you want more coverage or a relaxed fit, especially for bottoms. Size down for a snugger triangle top. Your hip measurement is the best guide for bottoms; your bust for tops.
Do you offer XS and XL?
Selected styles are available from XS to XL. Available sizes are shown on each product page — if a size isn't listed for a style, it isn't currently stocked in that range.
How do I convert my size to US or UK?
Use the size chart above: AU 8 = US 4 = UK 8 (Small), AU 10 = US 6 = UK 10 (Medium), AU 12 = US 8 = UK 12 (Large). Body measurements are the most reliable guide across regions.
Can I return swimwear if the size is wrong?
Yes. Unworn swimwear with the hygiene liner and tags intact can be returned within 30 days. See our Returns & Refund Policy for full details.
How should I care for my swimwear?
Rinse in cold water after each wear, hand wash gently and lay flat to dry. Avoid wringing, machine drying and prolonged contact with sunscreen, chlorine and rough surfaces to keep the fabric and shape lasting longer.
