Hunters- A nutral coat(black, navy, hunter, grey) with a light colored shirt with a ratchatcher coller(coral and blues are very popular this season!), kaki or tan breeches, and feild boots is the attire. Topped off with a black velvet helmet and black leather gloves. Your horse should have no boots, martingale, or breastplate. Saddle pad should be the fitted kind and white.
Show Jumping- for less formal shows and solid color polo and white or kahiki breeches is fine. For a more formal show, Your hunter jacket is fine with a stock shirt and stock tie. These should both be white. You can either wear kaki or white breeches with your feild boots, black velvet helmet and leather gloves.
Your horse's saddle pad can be any color, but white with a trim looks professinal, and most people use square pads. Any boots are acceptible, as are breastplates and martinglaes.
Dressage- Black, very very dark grey, or navy coat. White stock shirt with a stock tie, white breeches, feild boots. White gloves are used in upper levels, but your black leather gloves are appropriate. You can wear a hunt cap, but I
ALWAYS wear a black velvet helmet.
Your horse can not wear any leg protection, a white pad is used under usually black dressage tack. Or on a white horse, black saddle pads look great too.
Eventing- For dressage- same as the above dressage gear.
For Cross Country- Any color combination is acceptible. My colors are royal blue and magenta pink for mares and royal blue and black for geldings. You should wear a polo, certified cross country vest, helmet, gloves, breeches, and feild boots. Your horse can wear any leg protection(and I would recomend it strongly, I LOVE Woof boots), martingales and breastplates, and any color saddle pad.
For Stadium Jumping- just as said above.
Your hair for every disapline other than XC, should be done up in a hair net. I do mine in a braid or french braid, flip it under itself like a horse braid, then put my hair net on.
I would suggest getting a simple black show coat. It will be accepted by everyone!
