NET-A-PORTER
Zara
Ikea (love going in there to check out all the furniture displays!! too much fun!! :P)
Duty Free Shops in European Airports (so much cosmetics too choose from; I die!)
Mango (particularly the large on in Prague; has the best selection to any I have been to in the world.)
Hermes and Louis Vuitton boutiques (Hermes is just so classy and never crowded and LV always has amazing bags to look at!!)
And when shopping in the US I love to go to Bloomies. SO MUCH STUFF!!!!!!! You will never find half of it in Canada at that kind of price!
