It used to be that when you were younger, you wore a bikini and then when you reached a certain age (I’m not sure who decided what that age should be!) you started to wear a one piece swimsuit. However now one-piece bathing suits are definitely having a moment, with every age group choosing one as a stylish option for the beach or pool. In this article, you’ll find the best one-piece bathing suits for women.

Glamorous one-piece bathing suits

One-piece swimsuits pretty much went full circle. They went from being the glamorous swimwear to wear on the beaches of St Tropez in the 1950s, to being seen as somewhat frumpy.

Now, the boundaries have definitely blurred. You are just as likely to see a 20-something wearing a one-piece on the beach and a 50-something (or older) wearing a bikini. Who remembers Helen Mirren in that stunning red bikini vacationing in Puglia, Italy?

I wear a mixture of bikinis and swimsuits and think that a one-piece can look incredibly sophisticated. What could be more elegant that a stylish one-piece with a big, floppy sunhat and over-sized sunglasses.

Benefits of one-piece bathing suits for women

Apart from exuding elegance, a one-piece swimsuit can also be incredibly flattering for your figure.

You can opt for different neck styles to suit your body shape, from v-neck to halterneck, depending on what suits you best and how much coverage you prefer.

Tummy control swimwear: Flattering one-piece swimsuit options

Many swimsuits also offer figure flattering fabrics which suck you in in all the right places. Miraclesuit, for example, promises to give you the illusion of being 10 pounds lighter, making the brand one of the best choices when searching for one-piece bathing suits for women.

You could also take a look at Magicsuit, Tommy Bahama, and Spanx swimsuits if you are looking for slimming options, as well as British brand Boden.

Plus, you can always flatter your figure and express your style personality with a one-piece, opting for a playful print, some ruffles or an asymmetrical detail.

How to choose a one-piece swimsuit

Before I look at the best one-piece swimsuits in stores, here are a few tips for choosing a one piece.

1. Think about what you want to enhance and downplay

Just as with any other outfit in your closet, you can choose a swimwear style to flatter your body type.

For example, you could choose a suit with tummy control, or you could opt for one with padding, or without, to either emphasize or downplay your chest. If you want to look as if you have longer legs, choose a higher cut swimsuit.

If you are a pear shape, you could choose a swimsuit with a darker color on the bottom and a lighter shade on the top to draw the attention upwards.

You can try out these one piece tummy control swim dresses from Macy’s and Zando.

2. What is your suit for?

If you are snorkeling or doing some serious swimming, you are likely to want a totally different suit to if you are choosing one for a vacation at the beach.

Carole (above) has styled her swimwear to perfection with the addition of red sliders, big sunglasses, her woven beach bag and a pop of blue and white. And, of course, a slick of red lipstick.

3. What color do you want?

If you want a suit with longevity, you may want to choose a classic color like black, navy, red or white that will never date. But, you could opt for a print or the latest on-trend color for something different.

You can get a similar one piece bathing suit from La Blanca (regular and plus size) and Aqua Eve (plus size).

Below are 20 of the best swimsuit options for this summer. You’ll find all of the best one-piece bathing suits for women from classic black one-pieces to those which will pull you in, in all the right places, retro styles and playful prints.

1. Tummy control swimwear

If you aren’t confident about your tummy area, Miraclesuit is a great brand to try. The swimsuit below not only has ruching but also side panels for a slimming illusion.

2. One piece for women – classic black one-piece swimsuit

If a one-piece swimsuit is the most elegant piece of swimwear you can own, then a black one piece swimsuit has to be the most sophisticated, and classic, option you can choose.

Like the little black dress, the black one-piece swimsuit will never date. So, as long as you make sure you rinse it out when you have been swimming in chlorine-treated pools (otherwise, your suit will develop a saggy bottom), your black one-piece should last you year after year.

That’s why a black swimsuit can be considered an investment piece, just like any other investment piece in your closet, so you can look at spending a little more to get something you really love.

3. One piece swimwear – white one piece swimsuit

A white one-piece swimsuit can be tricky to wear, but it can also look beautiful if you find the right one.

I’m always worried when I wear white swimwear that it will be see-through, so it’s vital to choose a quality piece with thick enough material so you don’t end up showing off more than you intend to at the pool or the beach.

I like this swimsuit from Boden because of the asymmetric one-shoulder detail.You could pair it with shorts or a maxi skirt when you are ready to head from the beach for a spot of lunch.

4. One shoulder swmimsuit

Another lovely one shoulder swimsuit option is this Goddess suit (below) which is from the La Blanca range. You can opt for either blue or a pop of pink.

5. Strapless one piece swimsuit

If you are heading somewhere sunny and you want to make sure you don’t get tan lines (although, of course be sure to put plenty of high factor sun cream on!), then a strapless or bandeau swimsuit could be a stylish option.

6. One-piece swimsuit with skirt

If you prefer a little more coverage at the beach or pool than that offered by a traditional swimsuit, you could look for a swimsuit which has a built-in skirt.

It can be easier to find swimsuits with skirts for girls than for women. But you can try a lovely retro style which will look sophisticated and womanly rather than girly.

7. Halter one-piece swimsuit

Just as with any other piece of clothing, you can choose a swimsuit to suit your bodyshape. I always think a halterneck style is particularly flattering if you have an inverted triangle shape, although it can look beautiful on any shape.

The shaping of this swimsuit style (below) would also look lovely on hourglass and pear shapes.

8. Ruffle one piece bathing suit

The bardot-style bare shoulder look has been a key style for tops and dresses for the past few seasons, and the style has made it’s way to swimwear.

You could wear this style on or off the beach. Simply pop a maxi skirt on over your swimsuit and you’ll be ready to go to the bar or out for lunch.

9. Sexy one-piece bathing suit

I don’t know about you, but I always feel sexier in a one-piece bathing suit than I do a bikini. I think it’s because I feel more sophisticated.

I guess everyone’s idea of what is sexy is different, but I don’t necessarily think you have to be showing off any more flesh to sexy. You can just opt to bare a little bit of skin, choosing the area of your body that you feel most confident about.

10. Floral one piece swimsuit

Do you have a romantic side? Then perhaps you would love a pretty floral print rather than a block color on your swimsuit.

The pattern on the Cupshe swimsuit (below) almost has a watercolor feel to it and the piping makes it more flattering and gives the styling a bit of an edge.

11. Red one-piece swimsuit

Red can also be a very striking, classy color to wear by the pool or on the beach. You don’t have to choose a skimpy all-red piece if you don’t want a vibe which is too akin to Pamela Anderson in Baywatch. Instead, you could choose a style with flattering ruching like the Marks & Spencer suit with tummy control (below).

12. Low back one piece swimsuit

If your back is one of the favorite areas of your body, how about choosing a low-back swimsuit like the halter style (below), which has a flattering tie-up detailing at the back.

A 1950s styling particularly suits the one-piece swimsuit and can be beautifully flattering if you have an hourglass figure. You can channel your inner Marilyn Monroe in a polka dot retro shape swimsuit like the one-piece below.

14. High neck one piece swimsuit

While plenty of swimsuits have a low-cut neck, if you prefer to cover up your decolletage, you could look out for a swimsuit with a higher neckline, such as the COS suit below.

15. Long sleeve one piece swimsuit

Do you do a lot of snorkeling or water sports such as paddle boarding or surfing, for example? Then you may want to make sure you have some extra coverage, either for warmth or to protect your skin from the sun.

Take a look at the classic black suit (below) from Nike.

16. Black and white one-piece swimsuit

Just as a solid color black, red or white swimsuit can give you a very classy look, a monochrome suit is also very elegant.

The suit (below) from Sea Level has a flattering cross over style and ruching at the tummy area.

17. Yellow one piece swimsuit

While swimsuits often come in very classic neutrals, if you want to opt for something a little different, you could always add a bright pop of color, such as yellow.

18. Pink one piece swimsuit

Pastels are another lovely choice for your swimwear, but if you don’t want to go for all-over pink, you could choose a color-blocking style, such as the tummy control swimsuit below, which has a flattering wrap style across the bust.
