Why This Question Matters: Underwear and Swimwear Explained for Parents
As parents, ensuring our children's comfort and safety during water activities is paramount. A common question arises: Should kids wear underwear under their swimsuits? Understanding the design and purpose of swimwear helps address this concern effectively.
Swimsuits are specifically crafted to be worn without additional undergarments. They incorporate features that provide the necessary support, coverage, and protection, making extra layers unnecessary and potentially problematic.
What Swimsuits Are Designed to Do (And Why Underwear Isn’t Part of the Plan)
Swimwear serves multiple functions:
-
Hydrodynamics: Designed to reduce drag in the water, allowing for better movement.
-
Quick-drying materials: Fabrics like nylon and polyester dry rapidly, preventing prolonged moisture exposure.
-
Built-in linings: Provide modesty and support, eliminating the need for underwear.
Adding underwear can interfere with these functions, leading to discomfort and potential health risks.

Hygiene and Health: What Doctors Say About Wearing Underwear in Pools
Medical professionals advise against wearing underwear under swimsuits due to several health concerns:
-
Increased risk of infections: Wet underwear can create a breeding ground for bacteria and fungi, leading to urinary tract infections and yeast infections. SELF+1Norton Healthcare+1
-
Skin irritation: The combination of wet fabric and friction can cause chafing and rashes.
-
Chemical reactions: Underwear materials may not be resistant to chlorine or saltwater, leading to fabric degradation and potential skin reactions.
Ensuring children wear only appropriate swimwear helps mitigate these risks.
Comfort and Fit: How Extra Layers Can Impact Swim Performance
Adding underwear beneath a swimsuit can:
-
Restrict movement: Extra layers can hinder flexibility and range of motion.
-
Cause discomfort: Wet underwear can bunch up, leading to constant adjustments and distractions.
-
Increase drag: Additional fabric can slow down swimmers, affecting performance and enjoyment.
For optimal comfort and mobility, it's best for children to wear swimsuits as designed—without underwear.

Frequently Asked Questions
Should kids wear underwear under their swimsuits?
No—swimsuits are designed to be worn without underwear. Adding underwear can cause discomfort, bunching, and hygiene issues.
Is it unsanitary to wear underwear in a pool?
Yes. Underwear isn't made for chlorinated or saltwater, and it can carry bacteria or degrade quickly in wet conditions.
Are swimsuits lined to replace underwear?
Yes. Most high-quality swimsuits, like those from Bright & Bold Swimwear, include full lining for modesty and protection.
Can wearing underwear under a swimsuit cause rashes or irritation?
Yes. Wet cotton or synthetic underwear can trap moisture, leading to chafing or skin irritation.
Is it ever appropriate for kids to wear something under their swimsuit?
In rare cases, like medical needs or sensory sensitivities, parents may choose to add a thin, water-friendly layer.
What should my child wear under a swim shirt or rash guard?
Nothing is needed under a rash guard or swim shirt—they’re designed to be worn on bare skin or over a lined suit.
Should boys wear underwear under swim trunks?
No. Quality swim trunks typically have a built-in mesh lining that replaces the need for underwear.
Do girls need underwear under one-piece swimsuits or bikinis?
No. Lined girls’ swimwear is specifically designed to be worn alone for comfort, coverage, and hygiene.
What’s the difference between a lined and unlined swimsuit?
Lined suits provide extra protection and coverage—unlined suits may need extra care to ensure they’re thick enough and secure.
Can wearing underwear make it harder for kids to swim?
Yes. Underwear can absorb water and weigh kids down, making it harder to move freely and increasing drag in the water.
What should my child wear to swim class?
A properly fitting swimsuit with no extra layers, plus a towel, goggles, and swim cap if required.
Is it different for public vs. private pool rules?
Some public pools may prohibit underwear due to hygiene guidelines. Always check pool rules in advance.
