Gender Discrimination Needs to Stop

[Gramul]

So, male Elezen should be able to wear it and female Lalas shouldn't? =-x

Elezen men don't really have the curvature, but they do have the body of fashion model, where length and lithe help portray the look of the clothing itself more than anything.
Lalafell are made to look cute no matter what you put them in.

So...maybe they would pull it off a little better? In a weird way? But that's more of an apples/oranges deal.
In any case, you should ultimately wear what you are most comfortable in.
