Great shopping experienceI ran across Italist.com site while doing a specific search on the internet for a Dolce and Gabanna item. They didn't have the item I was looking for, but I browsed there sale items while I was there. The site works well and I enjoyed the shopping experience. I found a great pair of shoes that I ordered. The check out and delivery for the site was easy. The delivery arrived actually faster than I expected. I didn't have to contact customer service, which I consider a real bonus.
Louboutins Came Quick and Below RetailMy shoes came promptly and perfectly! Tracking updated quickly and my shoes arrived within 4 days. I love them so much and will wear them for years to come. Can’t wait for my next Italist purchase! Not to mention they were priced below retail... ugh I love Italist.
Quick Shipping, Quality ItemI had a very positive experience ordering an Isabel Marant skirt, delivered quickly, well packaged. Would def. shop again!
