I'm one of those people that hates carrying a purse or bag at any time, but especially at conventions! Who wants to have to keep putting their bag down and picking it up every time they get a photo taken?! Not me!!! But, it's usually a necessity so I just deal with it.
Now, though, I think I might just use one of these. Introducing the warrior pack purse!!!! I love this because you can wear it SO many different ways that there's definitely a way for you to wear it that won't really interfere with your cosplay, or, it'll be really easy to take off! Not only that, but with the right cosplay (can you say steampunk versions of like, anything?) it would look great!!
