Several people have stated that different brands fit differently (which I know from personal experience too). Given this, what good does a bra fitting do?
In my case, I tend to buy a bunch of new bras at once because I drive up to Annapolis for them. I get fitted and they know how the different brands run, size wise, so they bring various bras for me to try on that should fit. I come home with a few different styles in different sizes.
I understand your point. I guess I'm not really sure what size mine are because it depends on the bra.
But by them measuring me, they're able to find bras that fit/support well.
