Again, pretty big ranges in prices. I think I've seen show coats start off around $60 or so and go up to around $400 for nicer quality coats. Add in a few more hundred for custom coats. For clothing I'm a big fan of ebay
. I got a brand new Essex show shirt (originally $120) for $20! And a brand new Ariat hunt coat (originally $400) on clearance for $150. On a lot of things I have no qualms about buying gently used, and the clearance rack is my best friend.

to get ideas on price ranges. IMO, if you're not showing a lot or if you're growing there's no reason to spend a lot of money. Unless you want to.
The cost of a show horse is a completely different question. It all depends on the amount of training the horse has, the competitiveness of the horse, age, soundness, successful show history, where you're located, where the horse comes from (a horse from a big name trainer is going to cost more), etc. Our barn is a hunter/jumper show barn and the majority of the horses are around $15-35,000. The cheapest (fully trained show) horse is about $5,000 (he's actually worth a lot more, that's just what they paid), the most expensive is $150,000.
