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.

Great purchase for concertA little edgy Parisian and a lot of quality style. The Isabel Marant tee was perfectly cool and comfortable paired with the cross body Moncler bag which was a great choice for hands free dancing to Coldplay. And both pieces were on sale!!!!!
