Equetech Custom Riding Wear can no doubt make you a dressage coat with the pink accents. I love it.
Pink may seem like a kid's color or a junior color (junior rider pictured here), but I feel strongly that you can wear it at age fifty and older if you have the right attitude.
"I'm wearing Pink, dammit."
The fabric types they offer are wool and poly viscose part polyester, and partly a polymer made from plant cellulose. This fabric has a softness that makes it very comfortable to wear, even in summer.
