Damaged concert sweatshirt - can you guys help??

[Mokona]

Bristow was fabulous last night and I picked up a gray hoodie sweatshirt from the merchandise booth at the end of the show. She sort of folded it up and that was that and I took it back to the hotel.

Anyway, once we got back to the hotel, I noticed the sleeve of the sweatshirt was all muddy (no biggie - can wash it out), but there's like a snag on the sleeve of the shirt. Like a run in a nylon, sort of. I'm not sure any tailor could sew this up properly without it being obvious.

Do you guys have any idea what to do? I called Nissan Pavilion a few times today and got voicemail, and finally left a message for someone there asking if they could get me the name of the vendor.

Am I out of luck here? I know a good tailor, but even he may not be able to fix this, and it's such a pretty sweatshirt!
