This Bra-Size Calculator Is a Thing of Genius

Without the help of our bra-size calculator below, finding out (and updating) your bra size can be a time consuming and downright annoying thing. There are loads of great places where you can visit to get your bra fitted (and I do venture afield, as you'll see below), but the truth is that it's super-important to keep checking. Our bodies change fast (weight can fluctuate and our figures shift all the time) and wearing the wrong size bra can be rather damaging to your breast tissue. So, although we would always recommend getting fitted properly, it is a great idea to be able to scope out your own bra size from home. That way, you can be on top of things when you're too busy to visit a lingerie department every six months.

The first thing you'll learn? You've probably been wearing the wrong bra size for a long, long time. But don't worry—you're not alone in that mistake. It's incredibly common for people to assume that they have bigger backs they actually do. (Or be scared of having a larger cup size for the fear that it will limit their underwear options.) Here's where we step in to help.
