I bought two of these about 4 years ago from Nordstrom.  I wore them periodically w/o bra but because I'm a 30DD they did not provide enough support so they stayed in my drawer.  I exercise ALLOT and sports bras do not work for me, at all.  Way too much bounce, uncomfortable and give that uni-boob look, SO one day I had an idea ... I decided to try this cami OVER my bras.  Lo and behold it works really well to keep everything in place.  NOTHING MOVES and the combo lifts nicely and keeps things at the level they should be.  Once I discovered this formula I purchased three more (1 nude and 2 black).  They are great for this purpose; also just for general wear with my hip-hugger jeans to smooth a few bumps out to create that nice smooth line.  Nice quality too.  This merchant has a great price and speedy service.
