A one-piece bathing suit is a terrific look.

But, it’s also terrifically challenging when trying to find the right size and fit for most women.

Here are a few facts to help you find the right one.

One-piece bathing suits cover much of the torso, so manufacturers are forced to make several assumptions when designing them.

The first thing to know is that most one-piece suits are designed for a woman 5’4” to 5’8” tall.

The second assumption made is that the wearer is evenly proportioned between her top and bottom.

So, for example, if you wear a medium T-shirt, they assume you also wear a medium panty.

The third assumption is that you have an average height and an even proportioned waist and waistline — so not short or long waisted, and no major tummy.

Finally, for one-piece swimsuits sized with just a number like 6, 8, etc., an additional assumption is that your bra cup size is between a B cup and D cup.

So, if your height and proportions are within these parameters, you will find that most one-piece bathing suits fit you.

Recently, women are now able to find bra-sized one-piece suits.

They give… a much better & more flattering fit

...and come in bra sizing larger than a D cup.

However, the same torso assumptions are made — an even proportion and average height.

So, as an example, if your bra’s band size is a 36 (regardless of your cup size) the assumption for the torso fit is that of a size medium panty.

A band size of a 38 assumes the torso size of a large panty.

Sister sizing can be used with some success on cup sized one-piece suits.

Say your bra size is a 36G (D4) and your panty size is a large, or you have a long torso.

You could move from a 36G (D4) to a 38DDD (D3) and get more room for your hips, tummy or torso -- while keeping the same cup volume.

For women with hips and curves that don’t fall within all the one-piece swimsuit assumptions, you can still get a one-piece swimsuit look with a style called a tankini.

A tankini gives you a one-piece bathing suit look while actually being two pieces.

And there are many great advantages to this bathing suit style.

You can get a perfect fit because you pick your size for the top and the bottom.

It’s easier to put on and take off, bathroom breaks are simpler, and you can mix and match to get many looks… without having to buy an entirely new swimsuit.

As an example, here is a one-piece and a tankini side by side.

They pretty much look identical.

And with a tankini, you can buy several bottom styles to trade out to fit your needs.

So, with a tankini style, it doesn’t matter if you’re tall, petite, or have a tummy.

You can get a one-piece look that fits your figure perfectly.

Every woman can now wear the one-piece swimsuit look that truly fits and flatters.

How to Fit a One-Piece Swimsuit

We understand that shopping for swimwear can be challenging. You want to get a fit that makes you feel sexy and confident, and nothing can ruin your mood quite like an ill-fitting suit. The trick to finding the right one-piece for you is finding the right fit for your body type. This can be tricky because, as the one-piece is a single piece of fabric (as opposed to the separate pieces you get with a bikini), swimwear designers have to make a lot of decisions on how to size the midsection of the one-piece and how to set the proportions between the top and bottom of the suit. This can make finding the right fit more difficult for women with long torsos, petite body types, and different top and bottom proportions.

Just because you don’t have an average body type doesn’t mean a one-piece won’t work for you. All you need is some guidance on how to choose the right size and style.
