Wondering do you wear underwear with a bodysuit?
Most people don’t — bodysuits are designed to be worn on their own for a smooth, seamless fit. This guide breaks down when to skip underwear, when to wear it, and how different bodysuit fabrics change the answer.
Short answer:
Most of the time, no.
Bodysuits are designed to be worn without underwear so they lay flat, feel comfortable, and create a smooth silhouette under clothing.
Why Most People Skip Underwear With a Bodysuit
Bodysuits function like a second skin.
Adding underwear often creates problems instead of solving them.
• Prevents visible panty lines
• Keeps the fit smooth under jeans and skirts
• Avoids bunching at the hips or snap closure
• Enhances the overall look of the outfit
Most snap-crotch bodysuits are intentionally made to replace underwear.
Example: Everyday Stretch Bodysuits
A soft, stretchy bodysuit is meant to be worn on its own.
The Buttery Bodysuits are a perfect example.
They’re smooth, flexible, and designed to sit flush against the body — which is why underwear usually isn’t necessary.

For fitted looks, skipping underwear keeps the fabric seamless and clean.
When You Should Wear Underwear With a Bodysuit
There are exceptions.
Wear underwear if:
• The bodysuit is sheer or semi-sheer
• The fabric is very thin
• The bodysuit does not have snaps
• You want extra coverage or comfort
In these cases, a seamless thong is the best option.
Avoid thick seams or full briefs.
Sheer & Statement Bodysuits
Sheer styles are meant to be styled thoughtfully.
The Wet T-Shirt Bodysuit has a bold, see-through look, which means underwear may be worn depending on your comfort level and outfit styling.

For a clean look, many people still skip underwear — but seamless options work if added coverage is preferred.
Hygiene and Comfort Concerns
This is a common question.
Most bodysuits include a lined or gusseted crotch, similar to underwear.
For hygiene:
• Wash after each wear
• Avoid wearing all day in hot weather
• Choose breathable fabrics when possible
If underwear makes you feel more comfortable, it’s fine — fit and confidence matter most.
Does Fabric Type Matter?
Yes.
• Thick or stretchy bodysuits: no underwear needed
• Shapewear bodysuits: never wear underwear
• Sheer or mesh bodysuits: optional underwear
• Cotton or modal bodysuits: personal preference
Always check the look in natural lighting.
What Stylists Recommend
Stylists generally agree:
• Skip underwear for fitted bodysuits
• Use a seamless thong only when necessary
• Never layer underwear under shapewear
The goal is a smooth, uninterrupted line.
