Looking for Lightweight show jacket recommendations

I tend to get overheated very quickly while I ride so the added layer of a show coat makes everything worse.

What’s your favorite lightweight/breathable (mesh is a huge plus!) show coat? I have a longer torso so if it comes in long length that would also be very helpful.

I currently have the Dublin mesh coat and it’s a bit boxy and short on me.

I currently do hunters/Eq and am trying to stay under $250 but willing to consider all of my options.
