I have a riding assessment tomorrow at a barn I'm considering taking lessons at and I just realized I have no idea what to wear! It's summer, it's hot, and I don't usually worry about what to wear but it dawned on me that I've felt hot and sweaty after a ride before. It hadn't mattered then because I was with family - I didn't care. But this is a barn with other people around that I don't know yet. What if I sweat when I'm in the saddle? And I don't mean sweating from the brow. Saddles aren't exactly breathable material so surely someone has some advice on how to avoid embarrassing myself before I even get started?
