i think the stams have caused the most frenzy out of all the mj bags. the 05 petrol stam became really popular after lindsay lohan was pictured carrying it, and it was one of the harder to find colors.
my personal favorites are the venetia, stella, and the bags from the striping line.
definitely the stam as well although the crazy amount of knockoffs circling the streets is really killing it. i saw a pretty great knockoff for $40 and it makes me feel like even if someone were to buy the real thing, somebody else would just assume it'd be fake.
also, randomly saw that on bagborrowsteal, its denoted as an everyday bag!? members pay $30 for the week! could have swore that bag would have been diva level or whatever.
