It's tempting to wear the usual jeans, leggings, or tights during cold months, but I double dare you to try something new. Just look to Rachel Bilson for inspiration. Instead of donning the expected denim and top combo, the cutie paired a crisp white shirt with a pair of sharp trousers.
Note: these pants are all about the perfect fit. Ankle or cropped lengths can be flattering, just don't forget to complement them with fresh footwear.
