•  80% nylon 20% elastane
•  Hand wash only (rinsing in the shower is just fine), lay flat to dry

Bellows One Piece Torso Measurements

When sized and stretched properly, onewith will NOT dig in. Remember: you're a human being, and bodies are so much more dynamic than just numbers on a size chart. DM us if you want further guidance on best size!

NOTE: Do NOT expect our suits to be IDENTICAL to no-show underwear in fit. Do note that our suits do not have the same amount of stretchiness of standard no-show panty due to the inner grip strip & bonding.

Looking for cup sizes? We don't size by cup! Go with the measurement of the fullest part of your bust, and reference the Bust section of the chart. Or, shortcut alert 📣 order the same size you would for a camisole/tight tank!

"can I just order a few sizes and styles and return what doesn't fit???"
