As much as many people wish the leggings trend would just vanish, it doesn't seem to be going anywhere. Quite the contrary, really, it seems leggings, especially patterned ones, are going to be big for fall and perhaps even through the winter. The eighties has been back in a big way, especially on the Fall 2009 runways - so it's no surprise that this party girl trend doesn't want to leave.

American Apparel is, of course, the go-to brand for patterned leggings. We're crushing on these babies.   But at $42 a pop, getting a variety of patterns isn't exactly affordable. Enter cheap and chic favorite Forever21. They've jumped on the leggings bandwagon in a big way, with a variety of patterns available! Check out these groovy ones, or these black and white ones for just $9.80. Why spend over $40 when you can spend under $10?
