Wow, sorry guys, I'm such an assh*le, I forgot about this thread.
Fashion week is mid-Feb, early March at the latest. So it'll be way over when you come here.
However, favourite shops:
Jerome Gruet - rue St Roch - 75001 Paris
Great for summer totes and unusual accessories (I scored a delicious pair of coral earrings there). Cheaper than the US and definitely loads of choice. You can even custom order a colour combination if you can't find one that you love.
Repetto - rue de la Paix
Fabulous dancewear and recently, city shoes (ballet flats but not repetitive. Models are usually with a twist of some kind, which makes them really great)
The shop is going to be refurbished so they're moving to a temporary location (PM me before you come over and I'll check the address).
Printemps - boulevard Haussman
My very own shopping Mecca. It has everything. You get a 10% discount upon presentation of a foreign passport OR 12% detax if you are leaving the EU. There are coupons online you can print out.
Galeries Lafayette &
Bon Marché
I'm not quite a fan but there are big brands there and a different selection, so be sure to check them out if you haven't found what you wanted at the Printemps.
Conran Shop - next to the Bon Marché
Designer stuff. Mostly homeware but there are accessories and cute things like the Oromono cushion.
Good for a visit even if you can't afford anything:
Hermes - rue du Faubourg St Honore
The window displays are gorgeous and there are just so many things to see. They even sell the books there, so don't be afraid to walk in (during opening hours, Oprah).
Avenue Montaigne and the "
Triangle d'Or"
It's the It place with all the biggest luxury brands (Dior, Chanel, Chloe...)
Louis Vuitton - Champs Elysees
So many Vuitton, so little space. Check out the upper stories for clothing, shoes and runway stuff. Also some of the trunks. Ground floor dedicated to accessories.
Lancel - Champs Elysees
The flagstore is very conceptual in its architecture so it's worth a glance and if you can't afford Hermes or Vuitton, they offer good quality bags in a range of styles that you might like (I do, and when I was a student/freelance worker, they were my choice).
Places to eat
Any
Laduree tea rooms
Delicious cakes and macaroons in a very quaint setting and gorgeous drinks (tea, hot chocolate). Stay away from the coffee because it's expensive and nothing special compared to the rest of the selection.
Starbucks
Just kidding. I love Starbucks but it's not really French, is it
There are tons of little restaurants in Paris, so it's really a question of where you're going.
More to come as I think of it. Oh and if you want a tour guide of the area, hit me up, I'm quite happy to run around town looking at stores. <- This applies to anyone coming through Paris
