Lots of sports have dress codes. Having jeans matching jackets isn't more stupid than let say only "white or blue" gis in Judo, or only-white attire in some tennis tournaments. It's part of the folklore and many people are attached to traditions.
There are also many precedents of athletes challenging the dress-code, I can think of Serena Williams at French Tennis Open.
