i'm the sort of person who would wear something weird if the opportunity came up. which it has. but its a men's L and i'm a ladies S-M.
and i'm pretty tall (5'8) so i don't really want to look like a tomboy or a lesbian.

(with super tight skinny jeans and leather boots. maybe even a waist belt?)
You want a man's hockey sweater but you don't want to be perceived as a tomboy? O.o
If you're going to wear it out in public, I'd say that was a fruitless plea.
I think it would go nicely with blue jeans, a white tennis(or just pleated) skirt, white or blue tank top(on the inside), white t-shirt(on the inside), a ponytail(maybe a low, side ponytail), and normal white gym shoes.
White pants might work. I don't think the leather boots are a good idea.
Overall it's an interesting jersey, but it seems like the only place it would be appropriate is for casual times and sports games. Being awesomely cheap does have it's own plus though. Have you considered re-designing it? Like cutting off the sleeves to make it a long, sporty, sleeveless shirt?
Good Luck!
