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.

Professional site with excellent serviceFast delivery, fair prices and excellent service. Have used italist two times and absolutely pleased everytime. Could wish for more bags in Bottega Veneta and even more “saldi”, but really can’t complain :-)

I found the shoes II found the shoes I wanted for far less than what other websites were charging. Ordering was easy and my shoes arrived in a short time! I will definitely use this site again and would recommend it to others.
