Yet all females are born with them one shape or another.
Is this some femdom shizzel your harping for here?
Last I checked, boobs developed with puberty and a few women don't ever really develop boobs at all. I've never heard of a female born with C cups, living with them her entire life.
Seriously though, I agree that the customization of features was lacking. Boob size should've been a slider with a wide range of applicable sizes that morphed the clothes V wears. You look down and see a modest chest when you're wearing clothing instead of the F cups you put on V's chest prior to starting the game.
Character Appearance Customization is my biggest complaint about the game so far. It didn't at all live up to my expectations and even through gameplay it doesn't really carry through. It was certainly better than a game like Skyrim. I held the bar closer to PSO2, EVE Online and Black Desert Online.
