Ross is probably my favorite store in Austin. However, it's not for everybody so here comes my disclaimer. You have to be ready to dig, look around, possibly wait in line forever sometimes not be able to find anything.
BUT, this store has such variety that you will most likely always walk out there with something you love. I used to hit the clearance racks but their regular prices are so low that there's really not a major need to always hit the back of the store for extra discounts.
Make sure to check out their purses and shoes. They always have Nine West and other popular brands there. Also, if you are a frequent shopper at Express or New York, you might as well wait a bit when you see something in those stores, because most likely it will be at Ross in just a few months.
They always sell clothes that are in season and within the current styles but they also carry a lot of classic pieces.
