Ever since I got my knee-high boots, I've been wanting to put together an equestrian look. American Apparel has some awesome riding pants. They fit perfectly, and feel great! Love the material! (Lol -- and don't look for them in the menswear section though).
I already had some nice, brown kid leather gloves that were perfect. The riding crop as an accessory was just a fun thing I made just for the photos. It looks pretty good though (and stings well when you get smacked by it, hehehe).
