In fashion’s endless search for minute details to magnify and reinvent, the Chinese toggled closures known as pankou buttons are enjoying a resurgence, showing increased influence on luxury and premium labels ranging from adidas Originals to Lemaire.Sometimes referred to as a “frog button,” this traditional fastener appears in diverse forms, but is almost always characterized by a small loop on one side and a bead or knot on the other. There are utilitarian variants, such as those found in 1930s workwear, and more decorative variants, like the ornate designs found in Chinese formalwear. Why, then, did this ancient clothing detail find contemporary appeal, and how is it being reinterpreted today?The button’s international breakthrough as a mainstream trend roughly traces to 2025, when adidas Originals debuted its Tang jacket. This otherwise standard adidas track jacket, inspired by Tang suits, features knot-style pankou closures on top of the typical zipper. After gaining popularity as an Asia-exclusive, the jacket is making waves in the West, where the detail is showing up in inventive forms.Sartorial Silhouettes, Eastern InfluencesLike the adidas Tang jacket, interesting hybrid silhouettes are combining the pankou with Western details. At the Ralph Lauren FW26 show in Paris — the designer’s first men’s runway show in years — a black velvet tuxedo jacket featured ornate pankou closures. In more casual variants, the NYC-based label Sundae School has introduced the Hanbok Hoodie, featuring a diagonal pankou closure, and their new Teardrop Fleece boasts a singular pankou knot at the collar, as well.The button’s design is functionally similar to the toggle closures found on duffle coats traditionally worn by European sailors. Much like a pankou, a duffle toggle features a loop on one side and an elongated button on the other. The fusion of these particular styles has served as a jumping-off point for several designers. Kenzo’s Fall 2026 collection, designed by NIGO, features a navy jacket with a single pankou closure, decorated with traditional motifs and Westernized by a large duffle button. Yohji Yamamoto’s FW26 runway show presented a similar combination of ornate pankou closures paired with oversized duffle buttons, as did Sacai, emphasizing the braided detailing through elongated forms.These hybrid designs mirror the ways that the pankou has already been adapted by the West throughout history. In the 1930s, the pankou took on a simplified expression in deep blue work jackets, made to clothe Europe’s growing labor force. Eventually becoming prominent in France as “Bleu de Chine,” the chore coat-like style was reimagined by Lemaire in brown leather for its closing FW26 look.Heritage-Led InnovationWhile the pankou circulates globally, Chinese designers continue to recontextualize the heritage detail on their own terms. A prominent example in the global industry comes from CLOT, led by Chinese designer Edison Chen. In Ja
