I was just on CL looking at this. I am really biased because I love RiRi but I do agree that she has seemed really lost ever since this thing with C.Brown.
I saw a girl come into the club with something like that except that she had rhinestones on her nipples. Everyone just looked at her like she was crazy. In RiRi's case I think that she needed something to cover her nipples. She couldn't have rocked that jacket with a bare chest. She should have either worn a bra or worn a jacket that wasn't cut as wide across. Either way she's an entertainer so I think she can get away with it.
Love the makeup. On point as usual. Hollywood Nights, Show Orchid, NARS Schiap will all give you a similar look.
I also agree about her breasts. She has the best breasts I have seen in a long time. I WISH mine looked like that. I would wear shit like that all the time.
