i came up with an idea to help counteract the problem we all have of forgetting to bring our cloth bags into the grocery store when we go shopping. clothes with bags built in! the bags would fold up in such a way inside a coat or on a dress as to be barely noticeable, but when you needed them, they could be unsnapped or untied to accomodate your groceries. eventually all clothes would have them, just as many clothes have pockets or zippers, it would just be part of the way clothes were made. at first it might feel strange and awkward leaving the grocery store with various enormous lumps under our clothes, but i'm sure people would get used to it, and it would really cut down on the unnecessary bags.
