Return within 14 days of receiving your order for an exchange, online store credit or refund. Items must be returned in their original condition — unworn, unwashed, unaltered and with any labels, tags and hygiene stickers intact.
Please note that original and return shipping costs, duties and taxes are not refundable. Learn more at us.unepiece.com/returns.
UNE PIECE is available in womens sizes US 2 to 20 (AU 6 to 24). We follow standard sizing guidelines and make our products true to size.
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.
To keep your UNE PIECE looking beautiful, please carefully follow our care instructions:
- Cold hand wash.
- Do not soak, bleach or dry clean.
- Do not spin or tumble dry.
- Do not iron.
- Line dry out of direct sunlight.
- Do not pack or store when wet.
- Remove any excess water and dry without delay.
- Separate light colours from dark before washing.

Our swimwear is designed for a firm, flattering fit. If you find yourself between sizes, we recommend selecting the larger size for optimal comfort.
How to measure
Bust: Using a flexible tape measure, measure across the fullest part of your chest, ensuring the tape measure is straight across your back.
Underbust: Measure directly under your bust, where the band of a bra would sit.
Waist: Measure around your natural waistline — this is the narrowest part of your torso, usually right above your belly button.
Hips: Stand with your heels together and measure around the fullest part of your hips and bottom.
