Hi, I have great experience with Mytheresa, I actually feeling sorry for that company by seeing how many bad reviews it's got. By now I have ordered 6 items in total, no delay with delivery, no problem with return, absolutely love the way they packaged the items.
For example I had horrible experience with Cettire, when they have sent me a Balmain leather jacket instead of Balmain tweed blazer it was my first experience and of course last, I would never shop with them again, refund was 100$ less than what I paid, so I didn't even argue, I'm happy at least got the rest of money So I will keep shopping with Mytheresa and Farfetch, the sites I can trust by now.
