Might be a bit out of your budget but Le Fash NyY shirts are awesome! They are way worth it! They're super stretchy and comfortable! www.lefashny.com
A bit? Try almost double... I assume you are in some way affiliated with LeFash since there's a bunch of old shirt threads renewed with LeFash recommendations. To be honest, the LeFash shirts look nice under a jacket, but they look straight up goofy on their own. The pattern on the back is really weird if you aren't wearing a coat over it. JMHO.
The Ariat Sunstopper Show Shirt is supposed to be really nice...and at $50 it's less than half the price of my Essex Talent Yarn. I haven't tried it yet though so I can't say for sure. But I think it'll be my next show shirt purchase!
