I'm probably late to the game, but Forever 21 has some really cute socks right now! The anklet ones are a $1, longer ones are $3, and the tights are $10. The most amazing part is that they consist of at least 70% cotton (the tights are 68%), which is a rarity these days.
The Tribal tights look more expensive than they are, but I may have overstepped my twee line.
