What the experts know about the proper bra fit
"If you come across a bra with unusual
sizing, you can tell your salesperson you are 2, 5 or whatever
cup sizes larger than a D cup. She will then be able to ascertain
your correct cup size in that style."
Expert Advice on the Proper Cup Size
Bras for the most part are highly engineered and thoughtfully designed. It's not unusual for a bra design to be composed of as many as 40 pieces and findings. Though many bras are beautiful, bras are more about playing a supporting role than they are about fashion. We women need to understand what we are looking at when we try on a bra. Knowing what design features work best for our figure type will help us more easily identify the style of bra that suits our needs best.
Choose the Proper Cup Size
It is also a good idea to know how many sizes larger than a D cup you are. That way if you come across a bra with unusual sizing, you can tell your salesperson you are 2, 5 or whatever cup sizes larger than a D cup. She will then be able to ascertain your correct cup size in that style.
Finding a bra you love and discovering its size range stops just before your size can be frustrating. However, you may not be totally out of luck. Say you are a 40C and the bra you have found stops at 38DD. You MIGHT be able to wear the 38D or 38DD in that bra if the band doesn't feel too tight. Deviating from your traditional bra size is called the cup size game. Substituting bra sizes will work more successfully on women with band sizes 40 and above and D cups or larger because there is more breast tissue and body circumference to work with - a 2" band increase or a 1" bust line circumference increase is not as significant as it would be on a smaller framed person. However, having shared this game with you, it is always best to purchase your true size if you want to maximize proper fit.
