Quick Shipping, Quality ItemI had a very positive experience ordering an Isabel Marant skirt, delivered quickly, well packaged. Would def. shop again!

My favorite shopping siteI purchased a Longchamp black bag, I was searching for it everywhere, but due to the current hype on the brand, it wasn't available in my local boutique store, I got it through Italist for a much better price and received it within few days, From a fashionista and expert online shopper, I highly recommend this website,

Sweet DolceI love my Dolce Gabbana scarf! And the fast shipping was amazing. The price also very interesting

New to italistI ordered a pair of shoes and they arrived via dhl quicker than domestic shipping! Beautifully packaged and very happy with my purchase! Shipping fee was expensive though which is a pity. I would be shopping more often on italist if the shipping wasnt so costly.
