1. The first one I found is a Billy Cook that looks like this, but in a darker oil.Billy Cook Basket Stamped Roper Breast Strap bcbi12911 It's about a half hour away, and $35.
2. These are the ones that were posted in the other thread. There is no picture of the purple one and it's not listed in the description, but you can buy it under colour choices. I called and made sure it actually existed and wasn't a fluke. Tack Wholesale.com : Quality Horse Tack & Horse Supplies - Image Closeup
The pictures I'll post are of my saddle and my other purple tack. The Billy Cook one should match the leather on my saddle decently, but the other one is purple ostrich like the seat of my saddle. Would the purple breast collar be TOO much purple? I'm perfectly fine with being loud and obnoxious with tack. I am as a person anyway.
The picture of Abby with the tack is terrible because it was with my old phone (I got a new one with a nicer camera a couple days ago. ) and it was under fluorescent lights. She's the buckskin in my avatar if that's any indicator of how off the colour is. Every thing she's wearing is bright purple.
