Thanks for your feedback. I love Brian in the tee shirt, more so than the wife-beater (which I know is contrary to most of fandom).
My reason for Deb being the one that gave Brian the shirts was a part of my fic that I didn't include in the challenge. It would have taken the focus off of Justin, put it on Brian and changed the mood of the fic, which I didn't want to do here. It's in that ending, though, that the shirt could be tied to the scarf. I'm thinking of including that ending as an alternative when I post this to my journal. I haven't decided yet.
