In the HUS ring you can wear blue, black, grey, and I've even seen that dark brownish beige. I've seen jackets with pin stripes, plaid, and even solid. Mine has a light plaid. The English shirts are just about any color, even black. They don't wear the collar pins but they will wear embroidered initials or names on the rat catcher. They also wear the hunt cap and not the AES approved helmet although they will not frown apon it. The pants are mostly beige or grey. Light. They usually wear earrings to finish the picture, and black gloves.
In western for halter a nice pair of jeans and a solid button up (long sleeves) and a cowboy hat are fine. A blingy belt adds to the picture.
Showmanship outfits are usually very expensive blinged out costumes that match from hat to boot but a nice solid suit with a crisp button up shirt and hat will do.
In the the WP ring you can get away with a solid button up shirt, hat, boots, and chaps. Jewerly or scarf add to the picture. You can spice it up with a blingy shirt or belt. The attire can range anywhere from a $200 outfit to a $5000 depending but they can ride in the same ring without any problem.
"Be a best friend, tell the truth, and overuse I love you
Go to work, do your best, don't outsmart your common sense
Never let your prayin knees get lazy
And love like crazy"
