One Piece Swimsuit Plus Size for a perfect swim

Thanks to our one-piece swimsuit plus size charts, you can choose an option that will fit well and make your swimming days more vibrant. Find out the right size for your one-piece swimsuit in this post.

Should you size up in one-piece swimsuits? There’s a difference between when your swimsuit is wet or dry. Swim fabrics stretch when you’re in the water, so sizing down or staying true to size is better. If you’re staying dry most of the time, sizing up will improve fitting, since a dry swimming suit will stretch less.

Swimming has numerous benefits like building endurance, toning your muscles, increasing your heart rate, and relieving stress. However, your swimming sessions won’t feel so special when you are wearing a smaller or larger swimsuit than you need. Luckily, there are numerous sizes on the market, including plus-size swimsuits that can provide the right fit (skip straight to the one-piece swimsuit plus size chart).

How to Choose the Right Plus Size Swimsuit

Finding a swimsuit that meets your expectations as a plus-sized individual can be hectic. Fortunately, even when ordering swimsuits online, you can select the best size if you keep the right factors in mind. This section will discuss what to consider when choosing the right plus-size swimsuit.

1. Body Measurements

You’ll need a soft tape measure, an extra set of hands, and closely fitted clothes when taking body measurements. You should keep your body relaxed while your partner takes the body measurements to ensure they are as accurate as possible. Here’s how to measure different body parts when choosing a swimsuit size.

Bust

Take the tape measure around the largest point of the bust, under the arms, and across the back.

Waist

This is the area along your belly button. Measure around the natural waistline while keeping the tape parallel to the floor.

Hips

Measure around the fullest part of the hips with the tape measure going across the crotch in the front.

Once you have the measurements down, you can compare them with the ones in the swimsuit size charts to find the ideal size.

2. Body Type

You can also choose a swimsuit according to your body type. Plus-size doesn’t mean fat or obese; you have a larger body frame than most people. As such, you should consider your body type as you look for a suitable swimsuit.

3. Ample Coverage

The next thing to think about is the level of coverage you want from your swimsuit. You can wear a swimsuit that provides the same coverage as your underwear if you don’t know where to start. To keep everything nicely covered, you can wear complete coverage swimsuits. However, if you aren’t shy about showing some skin, you can choose those with less coverage.

4. Color

There are numerous color options when selecting swimsuits. You should choose a color that matches your personality and style. A black swimsuit is popular for people who like the contrast it creates against their skin. Alternatively, you can take a bright pattern that draws the attention of everyone on the beach.

If you stay true to what you love, choosing the right color won’t go wrong.

5. Fabric

The type of fabric you select will determine the level of comfort you feel and the ease of maintaining your swimsuit. As such, you should select something elastic that’ll adjust to the contour of your body. A comfortable stretch fabric that adheres well to your skin will provide tummy control so that you can look stylish while swimming.

6. Purpose

Are you going to a pool party, or is it a beach day on your calendar? The type of occasion can also affect the type of swimsuit you select. If you are headed to a private party, you might not feel shy enough to cover up your lower body. On the other hand, if you are going for a beach picnic on a public beach, you could feel more comfortable in a swimsuit that provides ample butt coverage.
