Female Kneeskin Swimsuit Size Guide

Female Kneeskin Swimsuit — Size Guide

These are training kneeskins — a comfortable, durable fit for daily training rather than an ultra-tight race suit. This chart is built from our actual pattern measurements and the stretch of our 320g poly-spandex, so always choose by your body measurements, not your usual clothing size — our sizing runs smaller than everyday clothing letter sizes.

22 XXXXXS 54–58 42–46 56–61
24 XXXXS 59–63 47–52 62–67
26 XXXS 64–68 53–58 68–73
28 XXS 69–73 59–63 74–79
30 XS 74–78 62–66 80–83
32 S 79–84 64–68 84–89
34 M 85–89 69–73 90–94
36 L 90–94 74–78 95–99
38 XL 95–99 79–83 100–104
40 XXL 100–104 84–88 105–110
42 XXXL 105–110 89–94 111–116
44 XXXXL 111–116 95–100 117–122
46 XXXXXL 117–122 101–106 123–128

The letter alias is a rough guide only — sizing runs smaller than everyday clothing, so please go by the bust measurement first. The kneeskin has a knee-length leg for extra coverage and a smooth, streamlined training fit.

How to measure

  • Bust: around the fullest part of your chest, under the arms.
  • Waist: around the narrowest part of your waist.
  • Hip: around the fullest part of your hips and seat.
  • Keep the tape snug but not tight, and level all the way around.

Getting the fit right

A note on our fabric: our 320g poly-spandex has plenty of stretch, so the chart gives a comfortable training fit.

  • Training / everyday: choose your true size from the chart for a comfortable, supportive fit.
  • Prefer it snug / race-style? Go one size down.
  • Between sizes? Take the larger for comfort, the smaller for a snugger fit.

Junior guide (rough reference only)

As a very rough age guide: 22 ≈ 5–6 years, 24 ≈ 7–8 years, 26 ≈ 9–10 years, 28 ≈ 11–12 years, 30 ≈ 13–14 years. Children vary enormously at the same age, so please measure and use the chart above rather than buying by age.
