I don't think they are the same girl. There are several moles on Misha B that do not appear on Selene B. (and please don't tell me about photoshop). There just doesn't seem to be any reason why MET would name two girls from the same photographer with different names. They may be sisters for all I know, like Andrea C & Danielle C or even twins. But it doesn't matter, I don't think they are the same.
