you think she even made herself so much work?
i think it went like that...
a chinese wholesale company sent her a catalogue of stuff that is "IN" right now, meaning that everyone is actually doing those things. her people flipped through that catalogue, chose the pieces most likely to end up on Paris herself (though she would never consider stuffing that junk into her own closet), Paris goes through the selection while she's driving to get some Starbucks or get her Herpes treated, calls her people, says "That's hot.".
Et voilá! Paris' own collection.
