Originally, I was exploring the type beside or below the sign, but I loved the simplicity of integrating the script into the print with no other "clutter" on the shirt. "Good to Go" has that "OK" vibe to it, but with GO as the operative word.
Sometimes the simplest solution is the right one. Like a manual transmission.
"Good to Go" is printed on a soft and lightweight, premium "dark nave" dyed combed cotton tee. Think more Ralph Lauren / Banana Republic – and less neighborhood car show shirt / 80 grit sandpaper.
