My mom made me a show shirt (similar to this but a different pattern https://www.etsy.com/dk-en/listing/225388366/girls-l-lime-green-westerrn-zip-show)
Black jeans or slacks
Black boots
Black cowboy hat (formed and cleaned)
Green bling belt with award buckle
Hair glued to my head with hairspray.
Simple makeup
Round earrings (similar to this https://www.etsy.com/listing/677059455/sale-set-of-4-large-horse-show-magnetic?ref=listing-shop-header-1)
That's what I did. Remember, any point you can earn is worth it. If you look neater than your competitor, that can push you into 1st in a tie breaker situation.
