This means being early. The evaluators like to see shorts and legs, not warm-ups when evaluating. Also, please tuck in your T-shirts.
Sloppy appearances mean sloppy play.
Wear clothing that is visible Wear socks that are striped, or colorful. Bright shorts are good. Something in your hair that is brightly colored if you use a scrunchy that is not interfering. Best color in shorts are red, purple, bright green, or bright blue. But I really like a sock that is bright and striped.
