Swimsuit Sizing Solved

When it comes to buying clothing and intimate apparel, many women prefer to do their shopping online. But even some of the most devoted online shoppers still prefer to buy their swimwear in a store because they think they need to try it on first. Many brands aren’t sized the same, different styles fit certain body types differently, and sometimes you can’t be sure the online retailer you’re buying from is giving you all the information you need to be confident with your purchase.

I understand that swimwear can be difficult to shop for. Because every body is unique, finding the right style, size and fit for your figure isn’t always easy. However, if you do it right, shopping for swimwear online doesn’t have to be such a challenge. Choosing the right size, brand, and online retailer can make a huge difference in your online swimwear shopping experience.

First, it’s very important that you understand how swimsuit sizing works. In this post, I’ll answer a few of the most commonly asked questions about swimsuit sizing.

How Do Swimsuit Sizes Work?

Swimsuit sizes take a few key measurements into account. These measurements include the circumference of the bust, waist, and hips. If you’re shopping for a one-piece, monikini or tankini, you may also want to measure and note the length of your torso. If you’re petite sized (meaning you have a shorter torso), this may impact how these styles may fit you.

Bra-sized swimwear, like your bra, uses your band and cup size. If you’re shopping for bra-sized swimwear and are larger than a D cup, you can use my exclusive Universal Cup Sizing™ System to determine your correct cup size in every bra and bra-sized swimwear style HerRoom carries. That’s hundreds of brands and thousands of styles!

How Do I Measure Myself for a Swimsuit?

You’ll need a tape measure. To make sure you’re getting the most accurate measurement, have someone else measure you. Make sure the tape measure is being held straight and snug – but not tight – around your body.

Bust: Keeping the tape measure parallel to the floor, measure the fullest part of your bust.

Waist: Measure around the narrowest part of your natural waistline.

Hips: Measure around the fullest part of your hips.

Underbust (optional): Keeping the tape measure parallel to the floor, measure around your underbust. This measurement will be helpful in finding your band size for bra-sized swimwear.

Torso (optional): Run the tape measure from the top of your shoulder through your legs and back up to your shoulder.

What Size Swimsuit Should I Buy?

Once you have all your measurements, you’ll be able to compare them to the size chart on the product page for every swimsuit available at HerRoom.

If your measurement falls between two sizes for the swimsuit size chart you’re consulting, I suggest that you select the larger size – unless the Fitter’s Comments indicate that the style runs large.
