What to look for when choosing a one-piece bathing suit

Choosing a bathing suit can be an arduous task, especially amid troves of new style trends every year. Bathing suit shopping this season boils down to the primary factors of fit, quality & price, and confidence & purpose.


This is the nonnegotiable consideration when buying beachwear. A conventional one-piece costume will cover your full torso and is the most modest option to a bikini. Onesies are the go-to wear for swim laps, water aerobics and any other water exercises.

Usually full-coverage bathing suits come with a deep low back, V-neck, 1 strap, or side cut-outs. It’s best to go with a high back one-piece to conceal your thighs, tummy, and hips. Some women need swimming costumes for religious reasons while some just enjoy the coverage it provides. Others just love it because it means not having enough sunscreen.

Endeavor to purchase a swimsuit that you fancy but not one that doesn’t fit you perfectly. The suit can be snugly but not uncomfortably taut on your body. If you don’t like showing much skin, pick something that doesn’t reveal much skin like a string bikini. If the bath-suit is baggy, it could be airy and will give you’re a hard time breat

Adjustability is another fitting factor that is a very important when choosing a one-piece bathing suit. If you have big bust, a wide-band halter that can be customized may be a great functionality. Swimsuits that feature an underwire or crisscrossing straps at the back can provide function and niftiness.

Move around win the costume to ensure that it responsive to your movements. Make walk-arounds, perform some jumping backs, tumble or bend over if you can. Try a bevy of movements to verify if the swimwear will not come off or expose you as you move around in it. For instance, if the swimsuit ruches up along your posterior when you’re walking, then it’s a red flag.

Quality & Price

Check the thickness of the swimwear to know if it’s durable. Touch and feel the material of the swimsuit. If it feels flimsy or cheap, then it’s not going to stand the test of time. Go for swimsuits that are made from materials that are thick and durable so that it holds up after washing or after a couple of ruffles at the lake or pool.

Even if the suit is well-lined and you cannot see through it, thinner fabrics will collapse over before long. Take a glimpse at yourself from behind to ensure that your bottom does not sag. Visually analyze the stitching, stretch, and compression. The suit should look neat and stable.

The way your backside looks in the bathing costume can also give you insights about its quality. Check to see the back of the beachwear is tight and flattering. If the bottom of the swimsuit looks saggy, or baggy, then it may not be a high-end swimsuit.

As for price, don’t break the bank just to buy a cute bikini; always buy what you can afford. Go for recommended brands instead. A $300 bathing wear is not necessarily a good costume. Yes, it might look cute but may not be made to last.

So, don’t be lured into the snare of false advertising. Price does not always indicate quality. Some brands are just pricier because of the brand name, the updates made to the previous version, and the ever-present effect of middlemen. So, if you’re thinking of cutting excesses while getting untampered quality, buy from a consumer brand that sells directly to you at affordable prices.

Confidence & purpose

Compare the suit’s color to your skin tone. Bathing suits come in a variety of hues and prints that you can express your style in. These colors enable you to come out sassy, chic, religious, modest or rebellious, depending on what you want to portray.

You should also consider your skin tone and if the color or design of the apparel appeals to it. For instance, you may choose a red and white polka dot bathing suit for a retro-look, a swimwear with pink roses emblazon on it for a strong romantic and feministic demeanor, or dark-brown beachwear that modifies your skin tone.

In addition, opt for bathing suits that have built-in components. While it can be exciting to have a necklace or earrings with the swimsuit, you can risk losing your jewelry while at the beach or poolside. Instead, get a swimsuit that has built-in hardware that glitters like jewelry without the risk of losing it. For instance, you may fancy a black one-piece swimsuit with silver accent along the neckline or a bright mauve-colored suit with rainbow-colored beads on the ends of the ties. You can also complete your outfit with a pair of comfy sandals, a wide-brimmed headwear, and a couple of sunglasses.

All in all, you’ll know when a bathing suit is right for you because it catches your eye right away and when you look confident and happy with it the moment you look in the mirror. Donning a bathing suit should make you feel like “James Bond blitzing a red corvette down the highway.”

For some women, wearing a swimsuit makes them live in the moment and not hassle with anything else. You want a swim suit that makes you feel hot, comfortable and beautiful.

Highlight, highlight, highlight

If you want to make a statement about your best features or make a sexy rendition of one of your worst qualities, the silhouette is just one apparel that can do the trick. Feel like showing off your erotic décolletage? Try on a plunging neckline like some small-busted Hollywood stars do on the red carpet. Have raging boobs? Get a leotard with ruffles to make them more enunciated. It patterns and embellishes the top that directs all eyes to your bust.


How can I get the right bathing suit size since I’ll be buying online?

Check your measurement and dimensions by carefully studying the size chart on the online store you’ll be buying from. Read the body-type recommendations and read the reviews to be well-informed about the sizing.

If you have done your research and have pinpointed your favorite costume, order them in two sizes. The first one should be the one you need as per the size chart while the second should be the size you feel is the most likely to fit.

Can I do all water-based activities in a one-piece bathing suit?

Keep in mind that there is a limited range of activities that you can perform with a one-piece bathing suit. If you’re out surfing swimming, paddle-boarding or running with the kids or just taking Insta shots by the pool, you’ll definitely need more coverage and support because you’d find yourself animating about rather than lounging.

String bikinis are more suitable for lounging, tanning or, to an extent, surfing. In which case, you might need a full piece with thick straps or long sleeve to shore you up.

What is the trendiest bathing suit?

In all our research, we find that one-piece swimwear is the best. It provides versatility thanks to its retro-style design and functionality. There are many sexual attributes that makes it stand out from the rest of the pile: deep plunge, one-shoulder, cut-outs, ruching, and off-the-shoulder.

One-pieces can also double-up as a body suit to give you a beach-to-bar look; another statement of its versatility. You can just wear some denim shorts over it or a skirt. The silhouette has been rebooted many times and now, it profiles virtually every body type no matter where you want support or accentuation. Belted one-pieces are an iteration slowly coming through this year.

How do I clean and care for my bathing suit?

Your beachwear can receive insults from pool chemicals, undesirable temperatures, sand, and sunscreen.

A well-built swimwear should last you for years on end, so it’s best to keep them looking great all the time. Almost every bathing suit is made from spandex so prompt cleaning is crucial as perspiration, sebum and body oils are reactive when in contact with elastic fabrics, causing them to breakdown and stretch. Discarding these impediments as soon as possible keeps your maillot in great shape.

The chlorine dissolved in pools can also damage the suits elasticity and color. While bathing suits are particularly liable to chlorine attack as it eats away the whiteness and turns it yellow.

A hot pool use of your suit will devastate the suit with a two-pronged onslaught of excessive chemicals and high temperature that will fade and strain the costume out quickly. Should you insist on wearing the suit in a hot tub, wear an older suit. Or, pick a suit that is made of 100% polyester and is chlorine-resistant. Cotton or other natural fibers will be punished in chlorinated water.

Always wash your suit in cold water after wearing it with a gentle liquid detergent or a spandex-friendly detergent. Handwashing is a good practice but don’t put the swimsuit in the dryer. Also, do not iron your costume. Washing should take around 10 minutes. The entire exercise should not be more than 30 minutes. Here are a few steps

  1. Rinse your bathing suit: do this in cool tap water. And for best results, allow it to marinate in cool water for 30 minutes as this will eradicate most of the chemicals including body oil, sand and salt that may damage the fabric
  2.  Drain and fill-up the sink: refill the basin with cool water and add a tablespoon of liquid detergent.
  3.  Submerge the bathing costume: turn the swimwear inside out and immerse it the solution. Swoosh for several minutes and rinse thoroughly.
  4.  Remove leftover water:  remove the suit from the water and wring water out of the fabric gently in a way that will not render it out of shape.
  5. Air-dry your bathing suit: spread the maillot out flat to dry out of direct sunlight. The sun’s UV rays can fade and render the fibers of your suit decrepit.

As you’ve already known in the washing guide, hanging the suit as against flattening them will strain the fibers and stretch them out. Instead, store the costume in a flat-lying position when it’s totally dry as any moistness will leave the suit at the mercy of mildews and other water-loving lifeforms. If you’re keeping it away for the season, store it in a garment bag and not in plastic. Plastic is a breeding ground for bacteria and mildew.

Repair your broken strap or address a small hole in the suit by hand-sewing small slits and rips in the material. Any bigger concern warrants the intervention of a professional tailor who’ll be more apt to sewing the more difficult spandex.

While having your best summer ever, you may drop some ketchup on your bathing suit at the beachside or allow a lot of sunscreen to come too close to the material. Simply apply a regular stain remover, and allow it to sit for one hour. Afterward, hand-wash, air-dry and store as directed.
