Nothing gets me up on my soap box quicker than the topic of a good-fitting bra. If you do one great thing for yourself this year, make sure each and every bra you buy is a perfect fit.
The size printed in the back of your bra is, at the end of the day, entirely useless. Choosing a new bra is not about you squeezing into a C-cup because you don’t want to be a D-cup, or cutting off your circulation in a size 12 because you’re sure you’re not a 14.
The size printed in the back is a fitting guide only and is exclusive to each bra, from one style to another and one brand to another. You must try on and preferably have somebody help you with fitting every single bra you buy. Even the smallest difference in cup or strap design can completely change the way a bra fits you.
The size of your bra is made up of two measurements: the under bust and the cup. The under-bust measurement relates to the width of your back. The measurements are translated into sizes: 10, 12, 14, 16, 18 and so on. These measurements are found by rounding up to the nearest 5 to 10cm. For example, a measurement of 73cm rounds up to 75cm which equates to a size 12.
The cup measurement relates to the size of the breast. Cup sizes are represented alphabetically A, B, C, D, DD, E and so on. The cup measurement should always be taken while wearing a bra. To determine your cup size, measure around the fullest part of the bust.
The difference between the under-bust measurement and the full bust measurement gives the cup fitting. A difference of 13cm needs an A cup, 15cm a B cup, 17cm a C cup and 19cm a D cup.
Remember, these measurements are taken as a guide to start the fitting. Any signs of sagging in your bust, loss of elasticity or tears in your existing bra all mean one thing: it’s time to get fitted for a new one.
