Just buy from ItalistI’ve been shopping Italist for about two years now for some Stone Island and Stone Island Shadow Project. I have to say, that I’ve been extremely happy with the packaging, price and shipping. All my items have arrived on time and in great condition. I would highly recommend shopping here as their prices, even for new drops, tend to be cheaper than the USA price points for Stone Island. You can definitely find some great deals when they go on sale too. Overall, I’m a very satisfied customer so far.

Fantastic experience, from start toFantastic experience, from start to finish! It took only 3 days for my item to arrive. The item came spotless, packaged and presented nicely. Prices are great, so is the ample choice of brands and collections. One of the top destinations for online shopping if you are after some genuine Italian clothes at great prices.
