Understanding How Your Bra is Meant to Work

Most of us put on our bras without a second thought about how they work. Understanding the purpose of the parts, however, can help you find that Holy Grail - a bra that fits really well and provides plenty of support.

Your average bra is a surprisingly complex collection of parts. While each section of the bra has a clear purpose, the interaction between the parts makes finding a bra that fits your body comfortably and provides appropriate support a difficult proposition. This is the very reason why it is estimated that some 70 percent of women wear the wrong size!

The single most important thing you need to understand is the concept of support. I'll be the first to admit it. For some reason, I just assumed the straps were meant to hold everything up. In truth, the straps are only supposed to provide a small amount of support with the band running around the bottom of the bra charged with doing most of the heavy lifting. I think of all those years of sore shoulders and headaches and just groan.

In regard to the support system, the bra has two key parts. The cup is designed to hold the breast. The band is designed to run around the bottom of the bra and provide support. These two factors make up the bra measurements. The measurements are typically noted by the band size, the length of the band, such as 36. The cup size is then represented by a letter running from A to DD. There is a big problem for women, however. The bra brands do not use exactly the same measurements. A 36C from Goddess Bras will not match the fit of a 36C from Le Mystere.

The wings of the bra are often overlooked, but also play an important role in getting a good fit. You might be wondering what exactly the wings are. They are the elastic cloth that runs from the edge of the bra cup under the shoulder and on to the back to make the horizontal strap across the back. This is one area where you can play a bit with the subjective feel of the fit. The wings should be taught enough that the support is provided around the bottom of the bra band. That being said, you can tighten and loosen them a bit to your personal taste so long as you meet this basic support requirement.

A bra that fits really well is a great bra. To find it, remember how your bra is supposed to work. Support should be from the bottom band, not the straps. Get this one element correct and you will get a much better fit.
