Shuai jiao is a generic term for chinese wrestling, not a particular style. Quality varies but it's mostly good since training involves competition. Chan Dung Sheng's style has a belt ranking system patterned after Kano's ranking system for Kodokan judo and uses the quilted cotton belts that were devised for judo competition about a hundred years ago. The jackets are canvas vests in the mongolian style and are not influenced by japanese dogi except for the material. Shuai jiao players also tend to follow chinese or western fashion and wear trousers or shorts instead of embroidered mongolian speedos. Shuai jiao exists in other schools, as well, with their own forms of ranking and costuming.
Jimmy Woo's san soo is twentieth century californian and carries on the ranking and uniforms established by Ari Emperado and Ed Parker for their systems. San sou is also a generic term for free fighting contests.
A few chinese styles have used uniforms resembling karate gi because that was what was available or expected when they came out of the woodwork and became commercial franchises, mostly in the 1950s and '60s. Until the Bruce Lee craze hit north america it was harder to find chinese-style uniforms outside of chinatowns and chinese community organizations. By the early '70s, though, dozens of kenpo/karate schools were changing their signs to read "Kung Fu" and parading around with chinese clothing and weapons and a bewildering variety of ranking systems leading up to the "supreme dragon grandmaster sensei" sort of nonsense. Mind you, i'm not saying a supposedly chinese style is not legitimate if it uses costumes or ranks from another culture. Ed Parker's kenpo was essentially ryukyu kempo basics, but he did learn some real chinese stuff. But, to me, it means: "Warning: Eclectic Mishmash Taught Here."
