Clothes shopping in Paris is difficult on a budget because clothing prices there are inflated IMO, but do have a look at Zara, H&M, Urbanoutfitters and Mango if you get a chance - they are more reasonably prices. Even if you can not afford anything, you HAVE to go looking along Champs Ellyses just to see the things and say you did haha. I agree with those who say spend your money on sightseeing - there is SO much to do in Paris! I have been five times and there is still TONS I can not wait to do. Last time was July this year, but the money was better.
