Hi, Im Aurora Borealis, a CD who has been on CDH for almost a year. The best cleavge Ive had came with wearing a breastplate, which cost me $350. There is no rift between boobs they look blended much like natural breasts.
There are many diffrent styles of breastplates to choose from many, many on the Internet from various retailers, with differing prices, etc. If you choose to wear ordinary forms held in place,by a bra you can do that too.
Hope this helps. Hugs, Aurora B.
