Taking Your Measurements
How to measure correctly
- Waist — wrap the tape around your natural waistline, keeping it level and snug but not tight.
- Hip — measure around the widest part of your hips and seat.
Take measurements directly against your skin for the most accurate result — not over clothing.
Size chart (centimetres)
| Size | Waist (cm) | Hip (cm) |
|---|---|---|
| S | 72 – 76 | 90 – 94 |
| M | 78 – 82 | 95 – 99 |
| L | 84 – 88 | 100 – 104 |
| XL | 90 – 96 | 105 – 110 |
These are guide measurements. Fit can vary slightly depending on the style.
Fit & Feel
I'm between sizes — which should I choose?
Go up a size for a more relaxed, comfortable fit. Stay true or size down for a closer, more performance-oriented feel. Our swim briefs are cut to sit close to the body by design.
Does the fabric stretch?
Yes. Every Jellyfish piece is made with a premium LYCRA XTRA LIFE + SOLARMAX blend — four-way stretch that moves with you and holds its shape through saltwater, chlorine, and repeated use.
Will it shrink after washing?
No. Our fabric is pre-treated and colourfast. Rinse in cold fresh water after each use and lay flat to dry in the shade — this keeps both the fabric and colour in the best condition for longer.
What if the size doesn't fit?
No problem. Contact our team within 30 days of delivery and we'll arrange an exchange for the right size. See our Exchanges & Returns page for full details.
