Quinn's style has definitely evolved since the start of Glee. It's just a shame that her character hasn't.
Her look now is a little tougher and a little less sweet with darker colours and boots instead of ballet flats. And though I do like what she's wearing still and I can see why the decision might have been made to make her less girlish, I can't help but wonder that since she's still the same manipulative, self-interested, deceitful, backstabbing bitch that perhaps it would have suited her just as well to remain a wolf in sheep's clothing.
Regardless I've picked out some pretty dresses for both her former and her current taste.
Nevertheless I'm still enjoying seeing Quinn in stronger colours and I think the dresses in the bottom row would suit her current look well.
