Letters and Numbers and Cup Size… OH MY! Making Sense of Bra Sizes By Michael A. Devlin, MD on December 15, 2014

What Do the Letters and Numbers Actually Mean?

What’s your bra size? The number portion of the size (the 34 in 34C for example) represents your band size or the measurement just below your breasts. To get this number, measure  tightly around your ribcage .Add five to this number. This is your band size.

The letter portion of your bra size is your cup size. Measure around your chest again this time placing the measuring tape at nipple level. This is your bust measurement. Get your cup size by subtracting your band size from your bust size. If the difference is a 1 your cup size is an A, 2 a B, 3 a C, etc.

Now you should have a letter and a number to use as your bra size Bear in mind that this is just a guide. Bra sizing isn’t standardized and each manufacturer determines their own fit. Use this as a starting point, but don’t be surprised if you have to experiment a bit to find the right fit.

Get a Fitting… or Try an App

I see many patients that come in and have been measured one time in their life and stick with that size. Please be aware that if you gain weight, lose weight or have been pregnant, your breast can and do change shape and size and therefore you may require multiple fittings.

If trying on bras with a professional sounds a bit uncomfortable to you, get your size on your smartphone. ThirdLove, a San Francisco bra company, has created a bra sizing app that uses your smartphone camera to determine your bra size all from the comfort of your own home.

Having a bra that fits can help you to love your breasts even more. If your breasts aren’t quite what you’d like, give us a call and schedule a breast surgery consultation. Whether you’re looking for a breast lift or implants, we’d love to help you love your body even more. To view my before and after photos of breast surgery click here: www.drdevlin.com/photogallery
