i have a 2yo NF pony should i show her in a bridle or a white halter? also would it be wrong to pull and plait then show her as a hunter pony? i have never shown ponies!
I think ideally the halter or a leather filly slip (like the halter only made out of leather) if you can. But its better you can control her in bridle if you get what I mean.
Don't see why you can't pull and plait her for HP classes too. It's allowed to pull their manes, just don't make it too thin or too short, you will need to compromise for the plaits!
