Best For: Bargain hunting

What Is It?: Navigating Yoox is like stepping into the warehouse at the end of Raiders of the Lost Ark.

A nightmare to navigate and rammed with brands you’ve never heard of, and some you will never want to hear of again, you’ll be just about to give up when you spot a Moncler parka at 80 percent off. Which almost makes all the legwork worth it.

Price: Every budget
