Size Guide

Every body is different. Here's everything you need to find the right size and fit for you.

Super Bikini Brief High Waist Racerback Swimwear Swim Shorts

Step one

How to measure

Two quick ways to find your size before you look at the charts.

Measure your high hip

Wrap a soft tape measure around your hip bones — the area where our low-rise styles sit. This is usually higher than your fullest hip measurement.

Half waist flat lay

Lay your underwear or swim bottoms flat and measure across the top of the waistband, unstretched. This is the most accurate way to match sizing to a garment you already own.

Fit tip For the best fit, use both measurements. If you are between sizes or prefer a more relaxed fit, we recommend sizing up.

Step two

How each style fits

Same size, different feel. Here's what to expect from each cut.

Firmest fit — built for laps

🏊 Swimwear fabric is designed to hold its shape in the water, so it will feel firmer than everyday underwear. If you prefer a more relaxed swim fit, size up.

Step three

Find your size

Select your range below and match your measurement to the chart.

📏

Quick note on fit before you look at the charts

Between sizes? Go snug for true to size or size up for a more relaxed fit. There's no wrong answer. Most customers find that sizing up feels more comfortable for everyday wear.

Teen sizing is based on body measurements, not age. Find the high hip measurement that matches and that's your size.

Girls Size	High Hip (cm)
8–10	60–66 cm
10–12	66–72 cm
12–14	72–78 cm
14–16	78–86 cm
16–18	86–94 cm

If your child is between sizes or prefers a more relaxed fit, sizing up is often more comfortable.

Measure around your high hip — the area over your hip bones where our low-rise styles sit. Sizing is based on this measurement, not the fullest part of the hip.

AU Size	High Hip (cm)	Half Waist Flat Lay (cm) ①
6	75–80 cm	30 cm
8	80–86 cm	32 cm
10	86–92 cm	34 cm
12	92–98 cm	36 cm
14	98–104 cm	38 cm
16	104–110 cm	40 cm
18	110–116 cm	42 cm
20	116–122 cm	44 cm
22	122–130 cm	46 cm
24	130–138 cm	48 cm

① Half waist flat lay: Lay your underwear flat and measure straight across the waistband, unstretched. A size 12 measures 34 cm flat, which equals approximately 68 cm around your body.

Important: These measurements are based on the high hip (hip bones), not the fullest part of the hips. If you're curvier through the hips or prefer a more relaxed fit, we recommend sizing up.

Period swimwear is sized to fit snugly in the water. Measure your high hip and match it to the chart. If you prefer a more relaxed swim fit, size up.

AU Size	High Hip (cm)	Half Waist Flat Lay (cm)
6	75–80 cm	31 cm
8	80–85 cm	33 cm
10	85–90 cm	35 cm
12	90–95 cm	37 cm
14	95–100 cm	39 cm
16	100–105 cm	41 cm
18	105–110 cm	43 cm
20	110–115 cm	45 cm

Swimwear fits more firmly than underwear and is designed to stay secure in the water. These measurements are based on the high hip. If you are between sizes or prefer a more relaxed fit, we recommend sizing up.

🌿

Every body is different — and so is every style.

Things that can affect fit: rise (low, mid, high waist), fabric type (cotton vs swim), personal comfort preference (firm vs relaxed).
