I’m going to the txt concert and I was wondering if I could bring a bag?

You can't bring in anything bigger than a small purse which will be searched at the door. Backpacks, messenger bags, camera bags, and large purses are prohibited. I'd check their FAQs page on their website for more details on what you can and can't bring into the venue :)

You can but they will check it.

Best thing to do is contact the concert venue and ask them. Pretty sure they will have some kind of security setup. Check on line also they might have information on items you can bring.
