If you look closely, you'll notice a recurring theme with celebrity outfits this summer: Everyone is wearing gold hoop earrings on vacation. Specifically, stars are crazy about New York–based designer Jennifer Fisher's versions—everyone from Emily Ratajkowski to Michelle Obama has worn her creations on trips this summer.

Fisher told Who What Wear how she's running with the massive popularity of the earrings: "Our brass hoops have changed our business in the last six months so much so that we have launched a version in fine and are going to continue to expand the collection in both brass and fine," she said. "We will also start to sell the fine hoops in singles in order to capitalize on the multiple piercing craze that has exploded in the last year."
