I've recently lost enough weight that none of my bras fit, and I couldn't seem to finds new ones that fit right, either.  I actually went into a store and asked for help.  I've since found that I need to buy Glamorise bras one band size larger than what I bought at my fitting.  This particular style not only runs the expected 2" short in the band, but the cup size is also small - my cup runneth over, if you catch my drift.  I've decided to keep it, since I think it will eventually fit, but it really should have fit like the other Glamorise bras I have in the same size.
