How do I fix my wardrobe blues?

I'm a 19 year old junior in college who wants to spice up her wardrobe. I don't have much money, and there are no clothing stores near my school to go shopping at. I'm just trying to find a few versatile, cheap things to add to my wardrobe in order to feel like I am changing something. I want to try to look ier and more fashion forward and less like an awkward high school student. I'm 5'8 and 115 lbs. Brown hair & eyes. I don't have many pairs of skinny jeans and it's chilly where I go to school. Any particular suggestions of items to buy, ideas on how to compile things differently, or stores to shop from? Thanks!
