The Ultimate Size Guide | How to Choose The Perfect Swimsuit

There's nothing like the embarrassment of an ill-fitting swimsuit. If yours is too big, it may shift and move around as you move around, or even allow something to pop out unexpectedly. Straps may slide off your shoulders and the back may look saggy. Finding the right size swimsuit isn't always easy, but putting in the work is worth it in the end. Atlantic Beach has the perfect swimsuit options for you, along with a few tips.

There are generally two options for swimsuits:

1. OS Size
2. General Size: S-M-L-XL

What does the OS stand for?

OS, in most cases, can be thought of as an abbreviation for "One Size", which some stores also interpret as "Overall Size" or "One Size Fit All".OS is often used to describe products with stretchy clothing and accessories, such as socks, leggings, bottoms, swimsuits, hats, knee pads, etc.

Does the OS a one size fit all?

There is no specific standard for OS, it just means the size that fits most people. It's actually quite confusing, different brands or different manufacturers almost always have different standards, but they all refer to the average body size, and different countries have different OS sizes.
Another misconception most people have is that OS clothing doesn't fit plus size people. This is not true. There is OS Clothing for plus-sized people and there is OS Clothing for medium-sized people. That's why we need to check the sizes in every store before buying.

But most Atlantic Beach swimsuits are available in sizes. The table below shows the universal intent of the s-m-l...  size of swimsuits, also you will find the size information on every swimwear product page. 

How do I find the right swimsuit for me?

1.Dress in tight clothing that doesn’t wrinkle.

When you take your own measurements, it is important that your clothing doesn’t interfere. Put on skin-tight clothing that won’t wrinkle up, like a tank top and leggings.[1]
- You can also wear your undergarments only if you feel comfortable doing so.
- Be sure to stand up straight during your measurements to get the most accuracy.

2.Wrap the tape measure around the fullest part of your bust.

Find the part of your chest that sticks out the furthest. Wrap the tape measure around this part of your bust to find out your bust size and write down this measurement.[2]
- Keep your arms straight down at your sides for a more accurate measurement.
- Make sure you pull the tape measure taut against your skin but not so tight that it digs in.

3.Measure your natural waistline underneath your ribs.

Find the bottom of your ribs by feeling along your torso. Put your hands just below your bottom ribs and above your belly button. Wrap your tape measure around your waistline and write that measurement down.[3]
- Your waistline is different than your hips and may not be as low as you think. Look for the area in your torso that dips in slightly on either side.
- Your waist measurement is especially important if you are looking for a high-waisted bikini.

4.Find your hips and measure the widest part of them.

Put your hands on either side of your torso near your pelvis. Feel for your hips by finding the area just above your rump. Wrap the tape measure around your hips and write down this measurement.

5.Wrap the tape measure length-wise around your torso to measure your upper body.

This measurement might feel slightly strange, but it is important to see how long your upper half is for an accurate size measurement. Wrap the tape measure around your torso vertically so it goes between your legs and over one shoulder before meeting the other end of the tape measure over your abdomen. [5]
- If you have a friend who helps measure you, you can take the tape measure from them and do this one yourself.

Look at the size chart on the website if you are shopping online.

Every brand is different and they often vary on what size fits which measurements. If you are shopping online, find the size chart for the swimsuit that you are looking at.

Match your hip and waist measurements to your swimsuit bottom size.

Most sizing charts are given in a table with sizes on one side and sample measurements on the other. Look up your measurements on this table to find the size that fits you best. Swimsuit sizes are usually XS, S, M, L, and XL. [7]
· If you are between sizes, it is best to buy one size smaller rather than one size larger. Swimsuits should not be baggy.
· Some swimsuit sizes are given in dress sizes and are indicated by numbers. You should follow your own measurements rather than your usual dress size in case they don't match.

Compare your bust and torso measurements with your swimsuit top size.

Swimsuit top sizes vary depending on how they are offered. Some sites will use XS, S, M, L, and XL, while others use bra sizes. Either way, find your swimsuit top size by matching your upper body measurements to the chart.

Combine all of your measurements if you are buying a one-piece.

One-piece swimsuit sizes are usually provided in one chart because they are only available in one size. Check the sizing charts that contain bust, torso, hip, and waist measurements to find your correct size.

No matter what you choose, remember that the right swimsuit size for you is whatever fits and feels best.
