Velour tracksuits are back this winter and the weird thing is that more stores are selling them but less people are wearing them! I (and many stylists) consider them as loungewear (to be worn at home) and the cotton ones to be worn when exercising or going for a walk. If you didn't buy one yet, check United Colours of Benneton, Giordano, Marks & Spencer, Bhs (they have them on sale), and Peacocks.
Benetton (also available with big crystalized logo)
Marks & Spenccer
For more fancy ones check Christian Audigier (Olympia Mall) and Juicy Couture (360 Mall)
