1 Don’t wear Jeans.
Who’s more legit?
Don’t wear Jeans, Jorts, Cargo Shorts, or Shorts/Pants without pockets (otherwise you can’t keep a ball in your pocket for your second serve and have to run around the court like a noobie).
2 Don’t wear a visor.
3 Don’t bend over and use your hands to pick up the ball.
4 Don’t wear that ugly tennis attire you see the pros wearing. They’re contractually forced to.
5 Do not stand around flat-footed all the time.
