Size & Fit Guide
Find your fit. Own your look. Our rompers and jumpsuits are designed for a modern, tailored silhouette—and the right size makes all the difference.
Use this guide to learn how each style fits, take your measurements, compare our size charts, and get a personalized recommendation with WAIR.
How RomperJack Fits
Rompers
RomperJack rompers have a slim, fitted silhouette through the chest, waist, and shorts. They're designed to look sharp rather than loose or oversized.
If you're between sizes, have broader shoulders or thighs, or simply prefer a little extra room, consider the larger size.
Jumpsuits
Our jumpsuits feature a European-inspired slim fit, with a streamlined upper body and tapered leg. They're cut for a tailored, modern look.
Because they're full-length, pay particular attention to the torso and rise. You should be able to sit, reach, and bend comfortably without pulling through the shoulders or crotch.
How to Measure Your Body
Use a flexible tape measure over lightweight clothing or against your skin. Keep it level and comfortably snug, not tight. Having someone help can improve accuracy.
Chest
Wrap the tape under your arms and around the fullest part of your chest.
Waist
Measure around your natural waist, generally above your belly button. Don't hold your stomach in.
Hips & Seat
Measure around the fullest part of your hips and seat so you have room to sit and move.
Height
Stand straight without shoes and measure from the floor to the top of your head.
Inseam
Measure from the crotch along the inside of your leg to your desired pant hem. Especially useful for jumpsuits.
Torso Length
Check how much length you need between your shoulder and crotch. Longer torsos often need extra room in a one-piece style.
Compare chest and waist measurements with the charts below. Height, weight, and length provide extra context; they should not replace a comfortable fit through your torso.
Romper Size Chart
