You’re probably stuck wearing the wrong bra size – here’s how to check

A staggering 80% of wearers are donning the wrong size, according to a report from fashion label Chums.

This common mistake can result in a wide range of surprising problems from ill-fitting clothing to neck and back .

The secret to securing a perfectly fitting bra lies in being able to measure yourself correctly before you buy.

Luckily for us, the lingerie experts are on a mission to save from the woes of poorly fitted bras by sharing the correct method for taking measurements at home.

Because different bra styles may fit differently, even if they’re the same size, it’s vital to not only measure precisely but also experiment with various styles to discover the ideal fit.

From identifying your band size to establishing your cup size, measuring yourself will ensure that your bra provides support and comfort without causing chafing, sagging or pain.

A well-fitted bra should sit comfortably around your ribcage without pinching, with cups that fully encompass your bust without leaving gaps or causing overflow.

Straps, on the other hand, should rest easily on your shoulders without slipping or leaving indentations.

How to measure your bra size

If taking your own measurements sounds complicated, don’t worry – it’s actually quite straightforward. It’s even easier if you have someone to assist you.

A bra size – such as 36D – consists of two elements. The number (36) refers to the band size, which measures the circumference of your chest, while the letter (D) indicates the cup size.

How to measure band size

To measure your band size, you’ll need a flexible tape measure – preferably one that records inches. The band size represents the circumference of your ribcage at the point where the bra band would sit.

1. While wearing a well-fitting bra, wrap the tape measure snugly around your ribcage, just under your bust.

2. Ensure the tape is level and lying flat against your body.

3. Take note of the measurement and then add three inches to this number.

4. If your final number is odd, round up to the next even number, as bra sizes typically come in even-numbered bands.

This final number will be your band size, and adjustments can be made using the different hook settings on your bra.

How to measure cup size

Cup size isn’t a direct volume measurement but rather the difference between two circumferences: your underbust (band size) and the fullest part of your bust.

1. Using the same tape measure, measure around the fullest part of your bust.

2. Ensure the tape is snug but not too tight, and that it remains level all the way around.

3. Note this measurement and subtract your underbust measurement from it.

4. Each inch of difference corresponds to a cup size.

Here’s a simple breakdown of cup sizing:

• 1-inch difference: A

• 2-inch difference: B

• 3-inch difference: C

• 4-inch difference: D

• 5-inch difference: DD

• 6-inch difference: E

• 7-inch difference: F

• 8-inch difference: FF

• 9-inch difference: G

• 10-inch difference: GG

• 11-inch difference: H

• 12-inch difference: HH

For larger sizes, the scale continues with I, J, JJ, K, L, LL, and M cups.

Once you’ve determined your bra size, it’s important to try on different styles to find the best fit for your shape and comfort preferences.
