Male clothing shopping in Paris

Department stores in Paris are generally very expensive and don't hold sales except twice a year. This seems very stupid, but it's the way they work. So generally I suggest not to waste time in the department stores unless you don't mind paying more than what you would pay in the US. There are a few standalone clothing store chains, not boutiques, which had men's clothing for more reasonable prices. These were:

• H&M, a Swedish clothier, is in the Forum Les Halles and on Rue de Rivoli. Of course, H&M now has many US locations.
  
• C&A, a chain started in the Netherlands, is on Rue de Rivoli
• Celio, a chain started in Paris, has several locations including Forum Les Halles and Rue de Rivoli
• Jules, a French chain, is in the Forum Les Halles

Actually, I'm sure these chains have other Paris locations, too. These were just more convenient for me.
