I find myself in the unfortunate position of not having a proper bra. I'm a size 44b. Closest I could find is a 40d. While it fits comfortably around the chest the cups sit empty. It's distracting and a little distressing. I've been looking at breast forms on breastformshop.com and at a set of inserts from xdress.com. I need guidance. Do I go for the inexpensive inserts that add 2 cup sizes or do I go with the expensive forms from breastformshop.com? Is either site trustworthy?
