Can you bring a fanny pack? I don't own anything with pockets and I would like to have a place to put my license, phone, and keys during the concert...

U might lose it

No, wristlet is your best bet

Don't do it

No wallet chains

5×7 or smaller. That is at all venues as far as I know. Comerica/DTE/CONCERTS

Last time I went, they were sending people back to their cars because of fanny packs and small clutches.

I dont want to say yes for sure. But if you do take one they will go through it like they did my boyfriends wallet.
