The cup should encase your breast tissue completely; meaning that the wires sit neatly around your breast, and shouldn’t sit on or dig into any of the tissue. If this is the case your cup size is too small.
Another sign your cup size is too small is if your breast tissue bulges over the top of the cup or out at the sides.
If the wires of your bra are pushed out anywhere the cup size is too small.
If the back band is too big, it won’t be able to sufficiently support your breasts.
Your back band should sit parallel with our front wires.
If you are able to pull the back band more than 2 inches away from the body with ease then it is too big.
If this is the case, then try a back size smaller, and as you go a back size smaller you may need a cup size bigger to compensate so try both.
Keep in mind ladies- it is the underband that should be providing most of your support… If your bra doesn’t fit correctly the straps will take the weight leaving dents in your shoulders (a clear sign something is up)
Remember that when finding a bra, it is the fit you are looking for. You cannot presume that you are a 36D in every brand!
A good bra lasts from 2 to five years… So spending the time to get properly fitted and finding a style you like is well worth the effort…It has been suggested that 90% of women wear an ill-fitting bra.
And when you find a great bra- BUY SEVERAL!
