10 Best Unisex One Piece Swimsuit in 2022

After years of being relegated to the back, the one-piece swimsuit makes a massive comeback. Today, many beach-goers and swimmers consider it a stylish yet athletic swimwear design more than the famous two-piece. This resurgence is due to more and more brands coming up with several methods with the use of high-quality fabrics. As assuring as one-piece swimsuits can be, shopping for one can be difficult and stressful at the same time.

This is because finding one that checks all your boxes can take a thorough adventure. And with summer fast approaching and a chance of you planning a trip to the beach or pool, it becomes more important to get an appropriate swimsuit.  To ease your task, here is a list of the best unisex one piece swimsuit.

Thankfully, regardless of your beliefs, one-piece swimsuits come in unisex designs. And both men and women can rely on them to have an excellent, fun-filled day during your visit to the waterside. These suits are comfortable, and you can be confident in them.

Is One Piece Swimsuit Ok for Both Gender?

Yes, wearing a one-piece swimsuit is acceptable for a man or woman. While the suit has been made famous by women, many men find comfort and confidence in wearing appropriate one-piece swimsuits. A one-piece swimsuit is as stylish, flattering, and physically appealing as a two-piece if you are a lady.

A one-piece swimsuit can help you appear more athletic while tucking away any undesirable features you don’t want on display if you are a man. Generally, one-piece swimsuits are comfortable, provide more coverage, are easy to wear, and are mostly cheaper. And if you feel insecure wearing a swimsuit, then a one-piece is your best bet at building your confidence.

Consider These Before Buying a Unisex One-Piece Swimsuit

Aside from fitting a one-piece swimsuit, it’s also essential to have a firm grip on what you want. This means taking into consideration the following factors:

1. Your Activity at the Beach

Before buying a one-piece swimsuit, consider the type of activities you will be engaging in when you get to the beach or the pool. This is because each swimsuit has a limit to its ability to move in the water. While most one-piece swimsuits will allow easy movement, they might not be suitable in specific instances. Also, you will have to factor in your exposure time to sunlight, as this will significantly determine the success or failure of your visit to the waters. For instance, if you will be diving at the pool or beach, a one-piece suit with a racer-back design or thick crisscross straps is best for such an event as it secures firmly on the body. 

2. Body Coverage

Another important consideration is the level of coverage provided. While one-piece swimsuits often provide ample body coverage, they still differ in the level of provision. High leg cuts, back cutouts, or string one-pieces are more suited for aesthetic displays and sunbathing, while more conservative one-pieces give you more coverage.

3. Fabric and Design

The fabric of a one-piece swimsuit certainly goes a long way in how well it performs. Add this to the design, and a perfect mix guarantees an incredible experience. Design features like seam sewing and quick-dry fabrics make for an easy transition from swimming to lounging. Also, one-piece swimsuits with inner lining might appeal to you as they provide extra support, coverage, and strength to your swimwear. This ensures you can have all the fun you want without worrying about your swimwear.

4. Overall Aesthetics

Your physical appearance in a one-piece swimsuit is also a deal-breaker. For this reason, I advise trying out as many one-pieces before settling down on which to purchase. If you have any feature you wish to conceal or accentuate, now will be a good time to factor it into your decision. All in all, you want to enjoy your time in the water rather than keeping an eye on your swimwear. Always try out a one-piece swimsuit with as many poses as possible to ensure it gives you that appealing presence.

Do You Wear Anything Under or Over A One-Piece Swimsuit?

Most one-piece swimsuits already note the need for undergarments and now have designs with features you have in an undergarment. For ladies, one-piece swimsuits regularly feature padded cups, underwire, or adjustable neck and shoulder straps to create support for the boobs. For men, extra lining in one-piece swimsuits provides excellent coverage for your crotch area.

TRENDING: Why Do Guys Wear Underwear Under Swimsuits?

You don’t need an undergarment alongside your swimsuit for the above reasons. But in the instance where you are renting a swimsuit, it’s a common practice to see people wear underwear. Some do this for hygiene purposes, but it’s not always advisable. Others might wear underwear if the swimsuit does not provide enough support or is made from a see-through material when wet.

Similarly, you don’t have to wear a short over your one-piece swimsuit. Although it’s a common practice, it still isn’t always appropriate, especially if you will be getting in the water. However, shorts like swim briefs, trunks, and swim shorts are wearable. But, if you plan on lounging at the waterside, then it’s perfectly ok to have shorts on your swimsuit.

You can create a stunning appearance with a wide range of matching shorts or pants. Regardless, shorts designed for swimming are excellent matches for your one-piece swimsuit either as part of your swimming dress or as a form of cover-up.
