Hi Everyone! I am in need of a big black purse/travel bag to carry on with me on the plane. I'd like one that can go over my shoulder and can still hold a lot of stuff without the worry of it breaking. I am contemplating the black Matelasse in both sizes. Matelasse owners, do you use your bags for this? Do you find that the quilted body makes it more durable and able to hold more? I have 3 bbags (2 leather, 1 pony). As lovely as the leather ones are, I worry that they would not be durable enough for this sort of duty. Please weigh in! or Thanks so much! ps--it's between this and a ysl muse. i like how the bbag is wider, for starters.
