They have a lot of masculine sets, just as many as they have feminine sets, in fact masculine sets are way easy to get, as they are usually "all class" sets for glam, and can be either earned with in game currency or crafted. Where as Feminine sets are either class locked or store purchased. The best looking dress in the game is level 80 Caster Locked (type 51 caster)which is great if I was a Caster Main on my actual main. But I play Ranged/Melee on my actual main character. And most of the outfits sets are overly masculine.
Edit: Adding the image of the type 51 caster set, best looking dress for females, and rather cool looking lab coat for males. I dislike that it's a gender flip set, and females can't wear the labcoat, and males can't wear the awesome dress.
and if you don't believe me that most of the ranged sets are masculine, look at this list:
