Quick answer

Measure your bust, waist, and hip at their fullest or narrowest points, then measure your torso from the shoulder seam over the bust to the crotch. Compare those numbers to the size chart and pick the size that matches your torso length first, since a bodysuit that is too short cannot be fixed by sizing up.

What you need before you start

A soft tape measure, a mirror, and a fitted top or bare skin are enough. Wear the bra or bralette you plan to wear under the bodysuit, because a padded bra can add an inch to your bust measurement and change which size you choose.

  • Soft tape measure, not a rigid ruler
  • A mirror or a second person to check the tape is level
  • The bra or bralette you will wear with the bodysuit
  • A notebook or phone to record numbers

Measure your bust, waist, and hip

Stand relaxed and breathe normally. For your bust, wrap the tape around the fullest part of your chest, keeping it level all the way around. For your waist, find the narrowest point above your belly button and below your ribs. For your hip, measure the fullest part of your seat, usually about 8 inches below your waist.

  • Bust: fullest part, tape level, arms down
  • Waist: narrowest point, not where your jeans sit
  • Hip: fullest part of your seat, feet together

How to measure torso length for a bodysuit

Torso length is the measurement most people skip, and it is the one that decides whether a bodysuit feels comfortable or pulls. Start the tape at the top of your shoulder, run it down over the fullest part of your bust, through your crotch, and back up to the starting point. Keep the tape snug but not tight. Write down that number in inches.

  • Start at the shoulder seam, not the neck
  • Go over the bust, not around it
  • End at the crotch and read the total length

Match your numbers to the size chart

Compare your torso length first, then bust and hip. If your torso is longer than the chart allows for your bust size, choose the size that gives you more length even if the bust is slightly roomy. A bodysuit that is too short will pull at the shoulders and ride up, and no amount of adjusting will fix it. If your torso is shorter, a smaller size may fit better through the body.

  • Torso length wins over bust when they conflict
  • Check the chart for each product, not a generic size
  • Note whether the fabric has stretch, like the 95% cotton and 5% spandex in the Crossback

Do a fit check before you commit

Put the bodysuit on and move: sit, reach overhead, and bend forward. The fabric should stay flat against your back and the crotch should not pull down. If the shoulders dig in or the front rides up, the torso is too short. If the fabric bunches at the waist, the torso is too long or the size is too big. Check the return policy before you cut tags, since some items like the Crossback bralette can be returned unworn within 14 days.

  • Sit and reach to test length
  • Check for pulling at the crotch or shoulders
  • Keep tags on until you are sure

Your measuring steps in order

  1. Step 1: Put on your usual bra: Wear the bra or bralette you will wear with the bodysuit. A padded bra can add an inch to your bust measurement and push you into the wrong size. Checkpoint: if you plan to go braless, measure without a bra instead.
  2. Step 2: Measure your bust: Wrap the tape around the fullest part of your chest, keeping it level. Keep arms down and breathe normally. Common mistake: pulling the tape too tight and getting a smaller number than your true size.
  3. Step 3: Measure your waist and hip: Find your natural waist at the narrowest point, then measure the fullest part of your hip. Write both numbers down. Common mistake: measuring over clothing or at the jeans waistband instead of your natural waist.
  4. Step 4: Measure your torso length: Start at the shoulder seam, run the tape over the fullest part of your bust, through the crotch, and back to the start. This is the number that decides if a bodysuit will be too short. Common mistake: measuring straight down the front and skipping the curve over the bust, which gives a short reading.
  5. Step 5: Compare to the size chart: Match your torso length first, then bust and hip. If your torso is longer than the chart allows for your bust size, size up for length even if the bust is slightly roomy. Checkpoint: if you are between sizes and your torso is long, choose the larger size.
  6. Step 6: Do a movement fit check: Put the bodysuit on and sit, reach overhead, and bend forward. The fabric should stay flat and the crotch should not pull down. If it pulls, the torso is too short. Next step: if it fails the fit check, return it unworn with tags on and try the next size or a different style.
