you know what... Out of a few of my shoulder bags (eg: BV, Petite Noe, Gucci tote, Chloe Side pocket paddy), this one is actually one of the better ones! The straps are cotton so they don't dig into your shoulder like the leather ones.. Also, they are wide enough so that the bag won't fall off your shoulders as you walk. It really is a good bag for uni/beach/travel, so roomy and the colours are all soo pretty! If I was to get another one, I'd probably get one in the navy striped MM though.. I can't really think of anything 'bad' about this bag, except it might be prone to colour transfer.. But I haven't heard anyone with that problem yet!
HTH
Thanks! I'll check out the brown MM and GM the next time I'm at LV. Does it fit under your arm nicely? Not too wide and bulky under the arm? I find the saleyas to be too wide to fit nicely under the arm.
