For those who don't want a completely flat chest with the ebody reborn body: The Teacups addon from Kottr is great! You can make your chest really really small, like almost flat but not quite while still being able to enjoy the curvy feel of the reborn body. Stores like Soapberry, FACS, Vincue and a few others also have items for that specific addon.
Also: Legacy Perky with the Petite Addon which also fits a lot of Perky items so you don't even need clothes specifically rigged for this addon!
Edit: I forgot about Technofolk which has a lot of unisex looking items for Legacy/Perky.
I'll also add a picture of my avi.
