How To Measure Your Bra Size
Find Your Size
A bra that fits you well will work harder than anything else in your wardrobe. Because the size, shape and firmness of your breasts change over time, what worked perfectly 10 years ago might not be right for you today. Seek out a bra-fit expert at a lingerie boutique or department store for expert help in determining your exact size and which styles best fit your shape. Or, grab a tape measure and do it yourself.
Here’s How
While wearing an unpadded bra – or no bra at all – wrap a soft tape measure snugly around your rib cage, just under your bust. Add five to the measurement (if the number is even, add six), and you’ve got your band size (32,34 etc).
Next, take a loose measurement across the fullest part of your bust.
The difference between the two measurements is your cup size.
- 1 inch = A
- 2 inches = B
- 3 inches = C
- 4 inches = D
- 5 inches = DD
- 6 inches = DDD

Hi JoJo,
Any hints on bra colour? I always thought you shouldn’t wear a black bra under a white shirt but am I just old-fashioned? How visible/invisible should those undergarments be?
I love seeing fashion bloggers writing about lingerie and the importance of a well fitting bra. I think its a huge part of what makes clothing look good and should be talked about a lot more online. Keep up the great work. xx
Thank you. I agree a properly fitted bra can make all the difference to an outfit and I think a lot of people overlook the importance of getting a professional to fit them. Jo x
