The last time I went to get a bra I went to Foley's and then went to a La De Da Lingere shop where I was custom fitted. There was a huge difference in what Foley's said I was, and what I ended up in.
Foley's Said I was a 52B based on what I measured. I've NEVER been a freaking B cup in my life. I knew the woman at foley's did not know what the heck she was talking about. The gal at Foley's recommended I go to La De Da Lingerie and get fitted. The gal at the bra shop said NEVER go by measuring - You need to find a bra that supports you and fits properly. The support is very important because your breast tissue can break down if you don't have proper support. I ended up in a Goddess Bra. and when I left the shop I felt a hundred times better. The new bra helped support the roll I have under my arms and actually gave me a waist that I didn't have before . You could see a huge difference in my shape and figure (yes the girls were more perky and I felt curvy instead of fat) and for the first time in my life, my straps did not slide down my shoulders. I highly recommend going to La-De-Da the price is higher, but the personalized service and expertise more than make up for it.
