Sorry I tried answer you last night but for some reason I cannot post from my tablet at home
Anyway, here’s a couple of videos
This one is from an MPT
AHS MPT 2013
This one is just an inspection, not MPT but you can see what the whip does (usually the professional handler and whip are a team and the whip person knows when to push, when to back off etc to make your mare look her best)- I think I actually am in a cameo in this one haha
For what to wear- in hand: basic khakis and farm polo (or similar look), under saddle- show clothes but not blingy, the ones I always worked were always in gawd awful temps in July/ Aug so a lot of people rode without jackets
There’s a bunch more videos on here Video By Patrick
