Very wearable. Swap your basic black leggings for pretty lace ones. Or add a lace t-shirt(forever21 post) to your jeans and t combo. For a party, wear a lace dress(party post).
Casual: Pair a polka dot top with jeans and flats for a pretty, feminine look.
Wear a polka dot dress for a fun but sophisticated party look.
Military: Wear a flowy sweater with skinny cargo pants and combat boots. Skinny cargo pants are a huge trend for fall/winter. They are an interesting alternative to jeans. Combat boots are another huge trend. For another military inspired look, see my post on Olivia Palermo, featuring a military jacket.
Wear a fair isle sweater with leggings and shearling ankle boots. Fair isle is a great update to your basic cozy sweater. Shearling ankle boots are really in this season. They are cozy but still fashionable.
