We show the easiest fabrics, fits, and simple tricks to feel good all day.

I don’t know anything (help me)

The fastest path (3 steps)
1) Measure bust 2) Measure waist 3) Measure hips Then pick a bodysuit style
Simple checklist
  • You measured bust, waist, and hips.
  • Your tape was snug, not tight.
  • If you are between sizes: for bodysuits, pick the feel you want (snug/smoothing = smaller, relaxed = bigger).

If something feels off, go to Fixes. We tell you exactly what to change.

Size Finder

Bodysuit sizing (super simple)
  • Bust is the fullest part of your chest.
  • Waist is the smallest part of your middle.
  • Hips is the fullest part of your hips/seat.

Bodysuits are often stretchy. But your torso length can matter too (some people feel “pulling” on the shoulders). If you often feel pulling, choose more stretch, adjustable straps, or a slightly bigger size.

1) Pick system 2) Pick bust 3) Pick waist 4) Pick hips 5) Tap button

Option A: Use measurements (best)






No tape measure?

Use a string. Wrap, mark it, then measure that length with a ruler.

Option B: I know my regular size already

Pick your everyday size system and size. We show the closest match + all conversions (Alpha / US / UK / EU / IT / FR / AU).



Bodysuit fit rule

If your bust/waist/hips are in different sizes, choose the size that fits the largest area for a smooth fit. If you want a relaxed feel, pick a stretchier fabric or size up.

Fit Rules

The 6 easy bodysuit fit rules

  • It must breathe: you can sit, bend, and raise your arms comfortably.
  • No digging at the leg openings: snug is okay, painful lines are not.
  • No pulling at the shoulders: if it feels like it’s “yanking,” you may need more stretch or a bigger size.
  • Bust should lie smooth: no gaping, no harsh pulling lines.
  • Bottom coverage should match your comfort: thong/cheeky/brief feels different—choose what you like.
  • Fabric changes everything: stretch + recovery = smooth fit; stiff lace/mesh can feel tighter.
Between sizes = choose your feel More stretch = easier Shaping = firmer

How to measure (super easy)

Bust
Tape around the fullest part of your chest. Keep it level.
Waist
Tape around the smallest part of your waist. Snug, not tight.
Hips
Tape around the fullest part of your hips/seat. Keep it level.
Torso tip (important for bodysuits)
If bodysuits often pull on your shoulders, choose more stretch, adjustable straps, or size up for comfort.

Find Your Bodysuit Fabrics

Fabrics decide the feel: soft vs firm, matte vs shiny, breathable vs warm. Answer 3 quick questions and we suggest fabrics to start with.

Soft + stretchy (most comfy)

  • Cotton rib: breathable, cozy, everyday favorite.
  • Jersey: soft stretch, easy movement.
  • Modal: very soft and smooth against skin.

Smooth + shaping

  • Nylon/spandex: sleek, smoothing, great for layering.
  • Ponte: thicker stretch, more structure.
  • Power mesh lining: adds hold (common in shapewear bodysuits).

Romantic textures

  • Lace: romantic; choose soft stretch lace for comfort.
  • Mesh: sheer and light; often layered.
  • Velvet: plush texture for glam nights.

Comfort tips

  • Hot weather: choose breathable (cotton rib, modal, lighter jersey).
  • Shaping styles: expect a firmer feel; if you hate tight, size up.
  • Sheer/lace: check lining placement to avoid scratchy spots.

Details That Matter

Stretch + recovery
Good stretch is not enough. Recovery means it snaps back and stays smooth (less sagging).
Torso comfort
If you feel pulling on shoulders or the crotch feels too tight, choose more stretch, adjustable straps, or a bigger size.
Bottom cut
Thong = least visible lines. Brief = more coverage. High-cut = leg-lengthening. Choose what feels best.
Closures
Snap crotch is most practical. Zippers can be edgy but should feel smooth against skin.
Straps + support
Adjustable straps help fit. Strapless needs stronger structure for security.
Lining
Lining can add comfort, opacity, and smoothing—especially for mesh and lace styles.

Fixes

Pick your issue. We tell you what to do.

It pulls on my shoulders
Choose more stretch, adjustable straps, or size up. Avoid very firm shapewear if you hate pulling.
It digs at the legs
Try a different bottom cut (brief/cheeky) or size up. Seamless edges often feel softer.
It’s tight at the bust
Size up or choose a neckline with more room (scoop/square). More stretch helps.
It’s tight at the waist
Choose a softer fabric or size up. Shaping bodysuits feel firmer by design.
It’s tight at the hips
Size up or choose a stretchier fabric. Thong cuts can feel “easier” than full coverage for some people.
The chest area is gaping
Try a smaller size, a higher neckline, or adjustable straps. A lined bust can also help.
It shows lines under pants
Choose thong, seamless edges, or smoother fabric (nylon/spandex). Avoid thick seams.

FAQ

Should I buy my exact size?
If it’s a shaping bodysuit, it will feel firmer. If you hate tight, size up. If it’s soft stretch, you can usually take your regular size.
What if bust/waist/hips are different sizes?
Choose the size that fits the largest area for a smooth fit. Then use stretch fabrics and adjustable straps to fine-tune comfort.
What is the safest bodysuit style?
Seamless everyday or snap crotch. They are comfortable, easy, and very wearable.
Do I need shapewear?
Not required. Shaping bodysuits can smooth your look, but comfort comes first.
