About Bra Sizing

We’ve all heard the statistics: 75% or 80% of all women are wearing the wrong bra size. Is it true? We sincerely hope not. The truth is that our bodies change all the time (even just within a year or two), as we gain or lose weight, as we gain or lose muscle tone with exercise, with pregnancy or nursing, and simply as we age. So even if you were wearing the right size just last year, you may need a change now. We’re here to help.

Measuring Band Size

There are two ways to measure your band size. The best bet is to do it both ways to see if you get a consistent measurement.

1. Bring the measuring tape around your back to the front, keeping it under the arms and bringing it up across to the middle of your chest (see image). If you get an odd number, round up to the next even number to get your band size.

2. Measure across the bottom of your band, directly under the bust and across your ribcage. Make sure to keep your measuring tape straight around the back to front. Again, if you get an odd number, round up to the next even number to get your band size.

Measuring Cup Size

This is where it gets tricky- if you already have a bra and can talk us through how it’s fitting, we might be better off stopping here- we can help you troubleshoot your fit. You can also Check Your Fit and see our Bra Fit Q&A for help assessing your fit. The first step (above) will tell us if you might be in the wrong band size. This one becomes much more subjective. Here’s how to do it:

1. Measure loosely around the fullest part of your bust, with the tape straight across and around your back, bringing it to the front.

2. Subtract your band measurement (from step 1) from this bust measurement. The difference calculates your bra size- each inch represents a cup size. For example, if you measure a 34 inch band size, and a 36 inch cup size, the difference is 2: which would indicate a B cup.
