So I finally hauled myself to Nordstrom last night for a bra fitting. I had been wearing a 34B and measured a 34D! The bras the salesgirl chose for me definitely fit really well and give me great shape. I noticed today, though, that the area under my arm (below the armpit, near where the wire meets the side of the bra) feels irritated. My old bras were way skimpier than these new ones, and they didn't cover that area at all, so it may be that I just need to get used to the feel of a bra with more coverage. The band size is definitely snug enough, and the bras are quite comfortable otherwise. I'm not red or chafed, just irritated. I just took the one I was wearing off and put on a jog bra instead. Is this normal? I tried on a few brands and these were by far the best fit. They are Natori. Bra experts, what are your thoughts?
