Allow me to present the Ukulele Go t-shirt! I wanted a ukulele t-shirt that didn’t explicitly say ukulele but was subtle enough for any other ukulele players to be able to recognise it. And so I came up with the 4 strings idea.
I just received mine back yesterday and it came out really well. The t-shirt quality is good, not too thin and the print seems pretty decent too. If you want to grab one I have them available to buy through Spreadshirt for £15.50. Mens and womens are available in loads of sizes.
