I've been in Paris during January & really it is hit or.miss as both locations could be busy.
Couture doesn't start until January 21 so there may not be as many tourists around but H clients
when they know there is the sale come from all over the world.
Clothes, scarves, shoes etc are usually plentiful at these sales but inventory changes all the time
Just go enjoy & perhaps you will luck out with the unexpected..... that's the fun of being in Paris..
Thank you! That is really good advice.
