Depends on the restrictions. The FFX and XIII outfits are gender specific, but ones such as Squall's (and other previous veteran gear) can be worn by both genders. If Rinoa's is added, it could very well be gender restricted because it doesn't really suit males that well and then we would be left with males complaining that female gear is being given favouritism. Perhaps Rinoa's dress from the graduation party could be added, but not sure about the blue outfit if it has a restriction you know.
