Many endurance riders originally come from the showing world (both western and English) and after years of boring, tan breeches, navy coats, and plain leather tack most enthusiastically embrace the available wild colors for both tack and clothing.
I went the other way. After many years of neon stripes, giraffe prints, sparkling greens, and other odd combinations, I was thrilled to start amassing my PLAIN schooling and showing wardrobe. Dressage clothing seemed so ... tasteful and elegant. I went berserk last summer shopping for WHITE breeches, WHITE show tops, WHITE stock ties, WHITE saddle pads, BLACK saddle pads, BLACK girths, BLACK bridles, BLACK coats, BLACK boots, BLACK half-chaps, BLACK helmets, and BLACK hair scrunchies. After I was through with that, I started searching for tasteful, dark schooling breeches with equally tasteful, fitted polo shirts for lessons.
After a 12-hour endurance race or a 20-mile conditioning ride, I was always really dirty, my tights might have a tear, and I was probably missing a toenail. I always felt like that kid, Pigpen, from Charlie Brown. Now, when I am done with a lesson, or after a schooling ride, I'm clean (mostly!), my body parts are usually where they belong, and I look cute!
Let me know if you spot any good deals on breeches or tops on-line!
