Last time I checked, unisex t-shirts were made to fit both genders.
Be glad you've got any real-life team t-shirt at all.
Unisex is more or less a PC marketing strategy; they're still using the cut of men's shirts. I have one fitted t-shirt to probably close to two dozen unisex T's, and there's a large difference. Unisex falls off of the boobs and gives you a block of a torso, fitted T's go under the boobs and give you a figure.
I'm actually quite curious as to why they didn't make fitted shirts, though, since in an interview Craig said that females outnumber males on Gaia (55% to 45% I believe was what was stated). No sense why they wouldn't have them made in a different cut designed for the female figure.
But I'm more inclined to make my own Gambino shirt than buy one anyway; $20 for the shirt itself and $12 for shipping is not worth it.
