If you've watched old Japanese samurai movies, you've probably noticed that although the samurai wore ornate and sometimes cumbersome ceremonial clothing when not in combat, they always doffed these costumes and wore simpler clothing once combat began. The popular wuxia writers (Jin Yong and Gu Long) generally do not describe the clothing of their characters at length. They might refer to the color of a costume, but won't describe it in such detail that one can actually picture the outfits. Are they form-fitting or baggy? Short-sleeved or long? The writers do not tell us. Consequently, when the TV/film producers are left to make adaptations, they have plenty of leeway to decide what the costumes should look like. The TV/film producers, of course, are thinking about how good the costumes look on TV/film...not whether they're practical costumes for martial arts combat. Consequently, we've gotten some very different and unusual costume designs for wuxia adaptions in the 1970s, 1980s, 1990s, and today. In each decade, however, the clothing, no matter how nice it looks onscreen, is often impractically cumbersome for actual combat. What do you imagine the clothing of wuxia characters to actually be like?
