The "Lafayette" gallery is a huge department store, mostly if not completely dedicated to the fashion world.
The place is beautiful inside and a huge building is dedicated to just women fashion. That's a bit disappointing as my interest could have been much higher, had they more items for men.
Most of the stores we saw were high-end to luxury, which meant we were just looking, not even close to touching and definitely not buying.
Still, it was a good place to get away from the heat, have some fun looking at what constitutes fashion for a part of Paris and one of my friends actually found some Nike sneakers he wanted, by chance, dare I say.
If you have the budget, you can go full on and buy many things. But most designer items are not useful for a regular day. Only for an outing at a chic event.
