Bra Fitting Room-Breast Shape CodesThese are sketches of some of the most common breast types. Please do not take offense at the labels - they were just the most descriptive and easiest to remember and not meant to be derogatory. You may be a combination of a couple of these shapes. Remember your shape code. Each bra's description tells which breast shape works the best with that bra shape. This aspect of fitting is just as important as measuring! Not pictured are two more codes of: NS for Narrow Set, where the breasts are close together and WS for Wide Set, where the breasts have more than average space between them (meaning you can put a hand's width between them).
