I seem to be the odd man out on this one: I only like souple! I like the way it ages and slouches a bit after a while, and being a really casual girl, I can wear it with old jeans or dress it up in the evening, I find the rigid too formal...but then I'm the one who likes slouchy bags in general so rigid ones just don't work for me....But it's a very personal thing, like bright colors v neutral ones..... LOL!
