When I visited our L.A. offices earlier this year, one of the editors, who lives 5437 miles away from me, was wearing a Rixo dress, a Staud bucket bag, and a pair of boots that I had in my suitcase back at the hotel. Instagram cult items, it seems, are like Happy Meals and Starbucks Frappuccinos—they are just as alluring whether you're in Paris or Philadelphia, London or Los Angeles. Globalization in fashion is nothing new—the likes of Zara, Topshop, and ASOS have all shipped internationally for some time, and red carpet pictures are circulated within minutes. What has changed, however, is the speed at which trends translate internationally. Small labels that are just finding their feet can become global sensations overnight, and outfit ideas cross continents in the time it takes to publish one Instagram picture.
