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.
