Support that moves with you
Swimwear shouldn’t hold you back. That’s why our designs for D+ busts combine secure support with a flattering fit — no bounce, no slip, no dig.
From ocean swims to beach runs, every suit is made to keep up with you, so you can focus on the adventure, not the adjustment.
Measure once, move freely
Did you know 80% of women wear the wrong bra size? The right measurements make all the difference in how your swimwear feels and performs. Grab a soft measuring tape to measure, then compare your measurements to the sizing chart below.
Underbust: measure snugly around your ribcage, just beneath your bust. Keep the tape parallel to the floor, exhale, and round to the nearest whole number.
Bust: measure around the fullest part of your bust, keeping the tape straight across your back.
Waist: measure at the narrowest part of your waist (around the belly button).
Hips: measure around the widest part of your hips and bum.

Your questions answered
How do I determine my swimwear size
Shopping online can be intimidating. Especially when looking for supportive swimwear. If you are unsure of your measurements and which size to order, just contact us and we can help.
If I am between sizes, should I order up or down a size?
Please view our size guide for more information. If you are between sizes, we recommend sizing down.
If you don’t do my size, will a sister size fit me?
Yes, sister sizes will fit you! If you need to go up a band size, simply just go down a cup size. If you are unsure, please check our size guide and how to find your perfect fit! And if you need any further help, just contact us.
Can I order two sizes to compare and return one?
Yes, you can order multiple sizes and return the one that doesn’t fit. Please ensure the tags are still attached, the item has not been worn and in its original condition. All postage in Australia will be covered by BounceDown.
