In recent years, fashion has increasingly turned to items that not only look beautiful but also have their own history. This is why distinctive Chinese knot fasteners — the so-called "frog fasteners," known in English as frog fasteners or frog buttons — have started to appear on runways, in street style, and even in mass market. They can be seen on jackets, dresses, coats, tops, bags, and even shoes. Items in the modern qipao style, linen kimonos with knot fasteners, and minimalist clothing with "Eastern" details have become particularly popular.

For many, this is just a decorative element, but in reality, these fasteners have an ancient tradition and their own name — pankou (pankou). They have been part of Chinese clothing culture for several centuries and combine practicality, symbolism, and craftsmanship.

Pankou is a textile fastener made from a cord or fabric strip that is twisted into a decorative knot. One part forms a loop, while the other is the "button" or knot that passes through it and secures the clothing. Unlike ordinary buttons, there are no hard parts here: the fastener is entirely textile.

It is precisely because of their shape that Europeans once began to call such fasteners "frogs" — the curved interweavings resembled the legs or silhouette of a small frog. This name became particularly established in Western military and theatrical fashion, where similar fasteners were used on uniforms and costumes.

However, Chinese pankou are much more than just hardware. In traditional clothing, they were a noticeable detail that could indicate status, taste, and even wishes for the wearer.

Interestingly, similar fasteners later appeared in European clothing. In the 19th century, "frog fasteners" were used on military uniforms, especially hussar ones. They served both practical and decorative functions. Due to the Orientalist fashion, Europe was actively borrowing elements of "Eastern" style at that time, often in a reinterpreted form.

This is why today you can find jackets with "frogs" that externally resemble Chinese pankou but originate from European military tradition. Fashion has reinterpreted this form several times — from theatrical costumes to boho style and modern avant-garde.

It is believed that the predecessors of pankou existed in China many centuries ago when clothing was primarily tied with ribbons and cords. Over time, these ties became increasingly complex and decorative. Pankou became particularly popular during the Qing dynasty when clothing types such as changshan and qipao spread.

Masters created dozens of knot forms: flowers, butterflies, clouds, spirals, double loops, symbols of happiness and longevity. Often, the fasteners were handmade from silk, and their weaving required great skill.

In traditional Chinese attire, pankou were almost never an accidental detail. They were chosen to match the fabric, color of the clothing, and even the occasion. For festive attire, more complex knots and bright colors were used, while for everyday wear, simpler and more subdued ones. In Chinese culture, knots have special significance. Traditional decorative weavings often symbolize harmony, infinity, prosperity, or connections between people. Because of this, pankou were sometimes regarded not just as fasteners but also as a kind of amulet.

Some forms of knots even received their own names and symbolic meanings. For example, double interweavings were associated with marital harmony, while round knots symbolized fullness and completeness.

Modern interest in pankou is linked to several fashion trends. Firstly, people have grown tired of overly "sterile" clothing without character. Textile knots add an element of handmade craftsmanship and texture to items.

Secondly, global fashion is experiencing a wave of interest in traditional Asian clothing. Following the popularity of Korean, Japanese, and Chinese aesthetics, designers have begun to actively incorporate elements of Eastern attire into modern cuts. Pankou fit perfectly into this trend: they are recognizable, decorative, yet minimalist at the same time.

It is also important that such fasteners pair well with the current trend for natural fabrics — linen, cotton, raw silk. Because of this, pankou can often be seen in so-called "quiet luxury," slow fashion, or zen minimalism clothing styles.
