The sleeveless jackets are mainly used in the modern Wushu Nan Quan (Southern Style) but also by the traditional (Southern) kung fu styles such as Choy Lee Fat, Hung Gar and Hop Gar. They are available in different colors of fine and supple satin; very similar to silk. Also available in fine black cotton (in combination with a red trim.)
About clothing sizes: the size is indicated in the body length in centimeters. So a pants or jacket size 170 means that it is suitable for someone with a body height of 170 cm. If you are of average build and you choose a suit that suits your height, it will fit loosely; the clothing is loose-fitting.
