Rarr Fitting Room
Grab a soft tape measure. Measure once, find your twin, then check the exact style you love.
Measure yourself
Measure over your underwear with the tape snug but not tight, and write your numbers down in cm.
Around your body
- 1BustAround the fullest part of your chest, keeping the tape parallel to the floor.
- 2UnderbustDirectly under your bust, where a bra band sits.
- 3WaistYour natural waist, the narrowest part of your torso, usually just above your belly button.
- 4HipThe fullest part of your hips and seat, usually 20–23cm below your natural waist.
- 5ThighAround the fullest part of one thigh, to compare with leg openings.
Your lengths
- 6Shoulder to underbust★ BrasFrom the top of your shoulder straight down to your underbust line.
- 7Shoulder to crotch★ BodysuitsFrom the top of your shoulder straight down to your crotch point.
- 8Waist to crotch★ Shorts & skortsFrom your natural waist straight down to your crotch.
Do you have a long or short torso?
It takes 10 seconds, and all you need is your hands.
- Place one hand just under your underbust, with your fingers pointing out towards the side of your body and your thumb and fingers together.
- Place your other hand directly underneath it, the same way.
- Check where your bottom pinky sits against your belly button.

Check your style
Every style fits a little differently. Pick a style and we’ll show you the size to buy, highlighted in the table. The ★ row is the measurement that matters most.
Which bodysuit suits your torso?
Enter your shoulder to crotch and your usual size to compare every bodysuit. Bodysuits are measured flat and stretch when worn, so your number will usually be longer than the garment.
Measure your lower thigh
Measure around your thigh 6 cm above your kneecap and we’ll show your knee pad size in each style.
Fabric matters too. All fabrics have a different amount of stretch, so the same size can fit slightly differently. Sparkle fabrics are generally a tighter knit than printed spandex, so if you’re between sizes in sparkle, go up.
All garment measurements are in cm. Flat means measured across the garment laid flat, so double it for the full circumference. Tap i to see why a measurement matters. 4XL and 5XL measurements are calculated from each style’s size steps.
