I would recommend rather to take a trip from Paris to Val d’Europe. This is about a 1 hour ride by RER (suburban underground train). Attache to the main commercial center, there is a nice “factory village” with big name brands selling last season’s collection at virtually half price. You will find Kenzo, Lancel, and also a few French names that are not found outside France. On top of that, you can get the VAT (12%) money back off the price.
The place is above your usual commercial center. Nothing ‘typically Parisian’ but if you are for brand shopping at low costs, that is the place for you.
