I don't care what they told you in the 90's about what looked dorky and what was rebellious-cool. this is what the cool kids are doing now. and anyway the one or two-unbuttoned thing has been done to death.
and while we have this great photo- please note:
the dylan-esque ray-ban style sunglasses are going to be here for a while. don't be hating just because you've already moved on to a style you borrowed from one of the golden girls.
