The Ultimate Guide to Swimwear Etiquette and Comfort

Should Women Wear Underwear with Their Swimsuits? A Guide to Swimwear Etiquette and Comfort

A common question in the world of swimwear is: Should women wear underwear under their swimsuits? While it may seem like a straightforward decision, the answer depends on comfort, swimsuit design, and the intended use of the swimwear. Let’s explore the reasons behind this question and uncover whether adding a layer of underwear is beneficial—or even necessary.

Understanding Swimsuit Design

Swimsuits are uniquely designed to be worn without underwear. Most swimsuits, whether bikinis, one-pieces, or tankinis, come with a built-in lining that serves the same purpose as underwear. This lining is made to offer comfort, support, and coverage in the water, where traditional underwear may not perform as well. Here’s why:

• Material Consideration: Swimsuit fabric, typically made from materials like nylon, polyester, and spandex, is crafted to withstand water exposure, whether it’s chlorinated pool water or saltwater from the ocean. Underwear fabrics, on the other hand, are generally not designed for prolonged water exposure and may lose shape or become see-through when wet.

• Hygiene and Breathability: Many swimsuits feature quick-drying fabrics that prevent moisture retention, which helps reduce the risk of bacterial growth. Traditional underwear, even if it’s made from cotton or other breathable materials, may hold onto moisture longer, increasing the risk of irritation and discomfort.

Key Reasons Not to Wear Underwear with Swimwear

For most women, adding an extra layer under swimwear is unnecessary and can even detract from the overall fit and function of the swimsuit. Here are some reasons why skipping underwear with swimsuits can be the better choice:

1. Enhanced Comfort: Underwear can create extra bulk, leading to discomfort and a less streamlined look. Swimwear is engineered to provide a snug fit that stays in place in the water; adding underwear may disrupt this secure fit.

2. Optimized Support and Coverage: Many swimsuits include additional features such as built-in bras, padding, and reinforced crotch linings that eliminate the need for underwear, providing all the support needed in a swim-specific design.

3. Avoiding Fabric Bunching: Underwear can shift or bunch up when layered under swimwear, especially in the water. This can result in uncomfortable, visible lines that disrupt the smooth, flattering fit that swimsuits are designed to offer.

Are There Any Situations Where Underwear Might Be Worn with a Swimsuit?

Though it’s generally unnecessary, there are a few scenarios where adding underwear could be a personal preference:

• Trying on Swimsuits: Many women opt to wear underwear while trying on swimsuits in stores to ensure hygiene. However, once you’ve purchased the swimsuit, it’s perfectly fine to go without underwear when wearing it to swim.

• Sheer or Unlined Swimsuits: In rare cases, particularly with fashion-focused swimwear that is unlined or semi-sheer, some women may choose to add a layer of coverage. However, selecting a fully lined swimsuit or one with added coverage can usually solve this issue.

Final Takeaway

For most swim occasions, wearing underwear under a swimsuit is neither necessary nor advisable. Swimsuits are built to provide adequate support, coverage, and comfort on their own, and adding underwear can often interfere with these features. Instead, focus on finding a well-designed swimsuit that meets your needs, whether you’re looking for extra support, full coverage, or a sleek fit that allows you to feel confident and comfortable in the water.
