Hi everyone! I'm pretty new to bbags but I feel like I am learning lots as I read through the threads, thanks ladies!! after looking at several pics, I think my first purchase is going to be a twiggy. but I have a few questions about them.. do twiggys look the same when they are filled vs non filled? or do they always hold up that "square box" kind of look or they only look like that when it is actually filled with stuff inside? if anyone has pics..can you post your twiggy filled and another pic of it unfilled? thanks everyone!! I hope I'm not being too annoying..
