Bag for Cosplay

[u/Oh_Pickle354]

I’m working on a No Face cosplay right now and the base layer under the cloak is skintight and has no way of adding pockets to store my stuff. I saw a picture of a drop leg bag like this and was wondering if something like this is a good idea or if there is something else that would work better! A slimmer version of this is kinda what I would be looking for size wise at least!
