What to Wear Under a One-Piece Swimsuit: A Complete Guide
One-piece swimsuits are popular for their comfort, style, and ease. But whether you’re headed to a beach day, a pool party, or some serious swim training, the question remains: Do you need to wear anything under a one-piece swimsuit? In this guide, we’ll break down the best practices for what to wear (or skip) underneath, tailored to different swim activities and personal comfort. By the end, you’ll be ready to confidently dive into your next adventure!
Should You Wear Anything Under a One-Piece Swimsuit?
Generally, one-piece swimsuits are designed to be worn without anything underneath. Most are crafted to fit snugly, with fabric that provides coverage, breathability, and even built-in support to keep you comfortable. Here’s why:
- Comfort: Extra layers can cause discomfort, especially when wet. Swimwear fabrics are created to be lightweight, quick-drying, and smooth against the skin, reducing chafing.
- Support: Many swimsuits include built-in bras or padding, providing support similar to a sports bra. This eliminates the need for extra layers.
- Fit & Appearance: A quality one-piece swimsuit offers enough coverage and support to feel secure. Adding layers can disrupt the fit, and may create visible lines or bunching under the suit.
Best Options for Wearing Under a One-Piece Swimsuit
If you’d prefer a little something extra or have unique comfort needs, consider these discreet options:
Seamless Panties
Seamless, lightweight panties are ideal for minimal visibility. They provide extra comfort without visible lines and are designed to stay smooth under swimwear. Opt for a skin-toned colour to keep it as discreet as possible.Swim Liner or Modesty Panties
Some brands offer swim-specific liners or modesty panties designed to fit under swimsuits. They’re made from fast-drying material and offer additional coverage without impacting fit.Nipple Covers or Breast Tape
If you’re looking for extra modesty on top, nipple covers or adhesive breast tape can be a good choice. These are thin and won’t interfere with the swimsuit’s structure, offering subtle coverage while maintaining the natural look of the swimsuit.Athletic Undergarments for Active Swim Sports
If your one-piece swimsuit is part of your athletic gear (think surfing or water aerobics), lightweight sports bras or compression garments specifically designed for water sports can provide additional support and prevent chafing.
Choosing Based on Your Swim Activities
Not all swimsuit needs are the same! Here’s what to consider for different water activities:
Water Sports: One-piece swimsuits made for performance activities (like surfing or paddleboarding) are usually built for full support, so avoid extra layers. Performance brands like Speedo design suits for streamlined comfort and minimal drag.
Lap Swimming: Competitive swimsuits are designed for speed and flexibility. Wearing something underneath could reduce range of motion. Check out options like the Speedo ProLT if you’re in need of something designed for movement.
Lounging by the Pool: If you’re more interested in lounging than swimming, wearing seamless undergarments or a light swim liner can offer extra comfort without impacting the look.
