It’s high time to retire that itsy-bitsy yellow polka-dot bikini. The crowds at the pool and the beach have spoken, and they’re shifting toward a new trend: one-piece bathing suits. These suits are not only stylish, but they are also flattering on all body types. Whether you’re looking for a sexy cut-out monokini or a more modest swimsuit, there’s an option for you. 

And just because summer’s ending doesn’t mean you have to hide away your new stockpile…one-piece swimsuits can be revamped from the beach into your daily wardrobe as a bodysuit! Pair it with a pair of boyfriend jeans or a skirt and you’ve got yourself a new outfit. Check out some of our favorites below.

How We Picked the Products

Methodology

As a fashionista myself, I wanted to be sure to offer multiple trendy options that appeal to different body types and style preferences as well as one more functional pick. Some of the criteria I took into consideration are as follows:

  • Material: A good swimsuit offers flexibility and is stain-resistant. These options fit the bill with a mix of nylon, spandex, and polyester.
  • Style Options: When possible, I chose brands that offered a variety of colors, prints, and designs. Buying a swimsuit is a personal choice, so you should be able to choose what you most feel comfortable in.
  • Multipurpose Functionality: These suits are not only appropriate for a beach vacation, but also as a possible addition to your daily wardrobe. Some options do this by easily doubling as a bodysuit.
  • Price: While these are certainly not high-end designer options, they are quality picks that come in at accessible prices in the $13 to $60 range.

Another feature that sets these bathing suits apart is soft bra cups—without underwire— which provide some additional support. That said, they might not provide enough support for women with larger chests. Follow the brand’s instructions on how to self-measure to find the right size for you.

Another significant feature of this monokini is that the spaghetti straps can be adjusted, allowing you to find the perfect fit for your height and body type. 

The only issue we see with this product is that the sizing is not very inclusive, so if you’re looking for a suit that’s smaller than a size 4 or larger than a 12, you’ll have to look elsewhere.

Things to Consider Before Buying a One-Piece Swimsuit

Whenever you choose a new piece of clothing to add to your wardrobe, you should focus on how it makes you feel. If you feel most confident in a sexy cut-out, go for it! If more coverage brings about that sense of confidence, focus your search there. 

That said, whichever design you choose, you should look out for the criteria I previously mentioned. Enduring construction will help you avoid having to buy a new suit after each season, materials are key for comfort and durability, functionality will help you make use of the suit even after the summer season is over, and of course… price. Think about how much you are willing to spend on a suit while still ensuring you get the quality you need. 

FAQs

Q: What is a 1 piece bathing suit called?

A one-piece bathing suit can be called just that (a one-piece) but also a monokini, which sometimes references a more modern suit that may feature halter tops, cut-outs, or other unique designs.

Q: Why do swimmers wear one piece?

This will depend on who you speak to. Some swimmers prefer a one piece because they appreciate a more modest look with more coverage. Others like that one-pieces are currently in style, with famous celebrities sporting them on almost a daily basis. Finally, most athletes prefer one-pieces to swim or dive in as they reduce friction and drag in the water, allowing them to reach higher speeds in the water (plus, they are way less likely to fall off!).

Q: What color swimsuit is the most slimming?

The rule of thumb with color is that black—and other darker colors—tends to elongate the torso while hiding places that we don’t want to flaunt. Vertical stripes and a ruched design can also achieve this appearance. You should feel comfortable and confident in your swimsuit, so play around with your favorite colors and styles and choose the one that feels best for you.

There are plenty of one-piece swimsuit options on the market today. If you’re looking for a stylish go-to piece that can be worn even outside of the summer season, look no further than the Dixperfect Women’s One Piece.
