Fantastic service at a great priceEverything was perfect: purchasing experience, communication, and shipping. Item (Junya Watanabe Men's jacket) arrived from overseas in perfect condition and securely packaged. Happy to have gotten it at a far better price than it was listed for by other online retailers (*cough* *cough* Farfetch). I think I'll be sticking with Italist for future designer purchases!
