To measure

Bust: Using a soft measuring tape, measure around the fullest part of the bust.

Underbust: Measure around your ribcage, just underneath the bust where the bra band sits.

Waist: Measure around the centre of the waist/torso.

Hip: Measure around the widest part of your hips and around your bottom. This will usually bring the tape measure right across the hip crease.

Are you between sizes?

Our swimsuits are constructed with a firm fit to flatter your shape. If you are between sizes, we recommend choosing the larger of the two sizes. For example, if you wear a size 10 in the top but a size 12 on the bottom (or vice versa) we recommend you purchase a size 12.

Are you tall and/or have a longer torso?

If you are tall and/or have a longer torso and sometimes find yourself between sizes, we recommend choosing the larger of the two sizes.

Mens

UNE PIECE is available in mens sizes XS to XXL.

Our swimwear is constructed with a tailored fit. If you would prefer a relaxed fit or are between sizes, we recommend choosing the larger of the two sizes.

Kids

UNE PIECE is available in girls sizes AU 5 to 14 and boys sizes AU 00 to 14.
