GoodWill, Consignment shops, it doesn't have to be from horse related companies. We buy jackets for $5 - $10 and use them for the local level because they can get pretty dirty. Same thing with pants, just nice black slacks or black jeans work fine. You don't have to spend a fortune to show. Bright colored tank tops work great under jackets for summer shows, same thing with just regular shirts, it also helps you add color for different horses without having to buy several colors of jackets and pants.
