Here in Portugal we have those Crocks stores too and there's always someone there buying something!
People here wear crocks all the time,with everything,it's just awful!Other thing that bothers me are Melissas,not the real ones,though I'm not quite fond of them either,but the fake ones,you can find them everywhere at cheap prices so everyone buys a pair.
The Nerd glasses trend,I guess that's what they're called,is reaching new levels around here since Primark started selling them for 1 euro,now everybody in my neighborhood wears glasses,unfortunately they don't look good on everyone...
