Do any of you know where I can find a really solid corset to wear under the gown? I haven't bought the dress, but want to have it so I can wear it when I try on the dresses. I want something that will be strong and supportive. I need it to smooth out the belly, cinch in the waist and support my large and heavy breasts. Don't know where I can find one in my size (16/18). I'm a 42 C.
