I've had lots of fairies, pricess ponies, and unicorns go through every year. My mini looked great in a purple tutu and wings..... One of my mares wore a toga for the costume contest a few weeks ago with ivy braided into her mane. I've had a few indian ponies pass through. The "bath" theme is always cute if you have a horse that tolerates a shower cap. Bob Marley was present this summer, as well as a balerina complete with tights..... We had a debate whether the mini would be Elvis or SpongeBob, Elvis won the debate (I was really hoping for spongebob...) I've seen lots of hippies. One of my favorites that was very original and easy was a teenager in my 4-H group. She wore one of my many bridesmaid dresses and put big goofey glasses, suspenders, and a crooked bow tie on her horse, they were "beauty and the geek".
