Need help finding a waist whittling longline bra or corset
Looking at the pics of me trying on my dress, I want to try to create a bit more waist to hip curve under it... I had planned on just wearing a microfiber, longline bra, and some Spanx... but I'd really like to find an undergarment with more powerful waist whittling... I don't know if I should go with a true corset, since the dress isn't heavily structured, and I don't want lacing, etc... to show through.
Ideally I'd like something in white (or nude), strapless, fairly low in back (doesn't have to be DEEP back, but I don't want it showing obviously) and hip length (I want it to go over the waistband of the spanx). Push up cups would be even better. I know there's a million bras out there that meet these requirements, but I specifically want something to give me a teensy waist.
