As a rule, I hate clothes shopping. But it always seems a little bit better when I remember I can shop at Plato's Closet. This store is a resale store featuring lightly worn brand names. They have a great selection of tops and bottoms for both guys and girls. They also sell dresses (no formal/prom dresses), shoes, earrings, bags and other random accessories--all slightly used and largely discounted. You can also sell all of the above at the store. Just bring your items in, hand them over to the staff, wait a few minutes, and get paid cash! The staff is usually friendly and helpful.
This new location is hidden on the west end of Odana, but it's definitely worth seeking out.
