Awhile back when I was at SFA in Nac, there was a guy would would were his kilt on occasion. I think for the most part it was well received.

I work now at the big library at UH, and I've caught sight of a few guys wearing more contemporary style kilts - like Utilikilts and such. Actually, come to think of it, last time I was in San Antonio I saw quite a few guys in traditional and contemporary style kilts. So, I'm pretty sure you'll do fine wearing yours at UTSA.

Good Luck!
