The jelly shoes decorating trend has become this summer's hottest footwear trend, with Red Velvet members Seulgi and Yeri joining K-pop idols like aespa and IVE's Lei in customizing transparent jelly shoes. Idols are adding various elements such as flowers, beads, ribbons, and colored charms to create personalized styles. aespa members used different colored elements for each member—Karina in blue, Ningning in green, Winter in yellow, and Giselle in pink—maintaining a cohesive tone with shimmering decorations like beads and sequins. IVE's Lei created a romantic vibe by adding pink flower elements to white jelly shoes, accessorizing them elegantly enough to wear at formal events like award ceremonies. For beginners, experts recommend choosing one main color and selecting matching elements rather than mixing multiple colors. The appeal of this trend lies in its versatility—the same shoe can create different moods depending on the decorative elements added, from quirky to lovely to minimalist styles.
