How to get rid of horsey smell on my clothes?

My clothes absolutley reek of horses. Friends and family keep saying how much I smell of horses and my nice clothes are starting to smell too. I used to like the smell but now it's really annoying. My horses don't like it when I smell of perfume or spray, they prefer the smell of themselves, and that's about the only benefit. My coats are always in the wash, and I usually get the smell in the evening, after stuffing haynets, changing rugs etc. Any tips?
