I've no problem with it. What I do wonder is if doing a female-to-male cosplay would be acceptable, however. Given that anime tend to be flush with interesting female character designs, and for men, ah, not nearly as vibrant, it would be an interesting creative exercise.
I'm a U.S. Navy Sailor. I also make costumes sometimes. Probably more often, now that Uncle Sam pays me well.
I cosplayed Thane Krios and have a fondness for projects that are way over my head.
