I've tried all the shaping cami's out there, and this is the one to get.
It's half the price of the Sassybax, and supports better!  It STAYS DOWN; NO ROLLING UP at all! It also supports the breasts from the side and below to produce a beautiful cleavage. NO UNIBOOB with this! I'm a 36C bra and can wear this braless.  I'm now 50 and starting to get the dreaded Menopause Middle, but this delivers FIRM control and holds you in.  I do wish it came in more colors. Age 50, 5'2", 36C, chubby. I bought size 36.
