Size Guide

Isla Swim — Size Guide

Our bikinis are designed with a sculpting, minimal fit.
If you prefer a little more coverage or you're between sizes,
WE ALWAYS RECOMMEND SIZING UP.

Tops

Use your usual bra size as a guide:

Bra size Isla Swim size
80A/B, 85A XS
80C, 85B, 90A/B S
80D, 85C/D, 90C M
85E, 90D, 95C L
90E, 95D/E, 100E XL

Between two sizes? We recommend choosing the larger size, as our bikinis are designed with a smaller, more flattering fit.

Bottoms

Choose your usual underwear size.

EU size Hip measurement Isla Swim size
32–34 83–89 cm XS
36 90–96 cm S
38 97–101 cm M
40 102–106 cm L
42 107–113 cm XL

Between two sizes? We recommend choosing the larger size, as our bikini bottoms have a cheeky, minimal-cut fit.

How to measure your hips

Measure around the fullest part of your hips, keeping the tape measure snug against your body without pulling it tight.

TIP: If you don't have a measuring tape, use a piece of string and measure it against a ruler.
