not a crossbody- but i have the anna corinna jet setter jr. tote in matte black and it is a huge, great, throw everything in bag that can still sit really comfortably on my shoulder. i know its not mj- but cute still.
i also saw the Marc by Marc Jacobs Dr Q Hiller Hobo in black today and it is pretty cute- I thought about buying it but decided I didn't need two big black bags.
good luck!
ps. you know the trish can be worn snugly crossbody?
ooh...i second the ac jsj. that's my travel bag. and it's WAY cheaper than MJ...
yep, the trish can be worn crossbody for sure! but it is sooo heavy...
