A wonderful shopping experience!So many times I’ve seen items of interest on italist and I finally decided to purchase some amazing Prada boots that I’d never seen elsewhere. They shipped here in a flash and they are superb! I will definitely be back for more beautiful items.

Fantastic price and gorgeous bagI was hunting for another bag when one of their sale bags caught my eye. At 40% off, it was an incredible deal. The bag arrived in 4 days, beautifully packaged with tags and on time. Looking f9rward to shop some more delicious bags from Italist this year... if you are on the fence about a bag, definitely go and check them out!!!

On time and exactly what I wantedI love, love, love my Golden Goose Super Star sparkly sneakers so much. I didn't want to take them off. They pacify the 2 year old in me. :-)
