There are several shirts worn here, but none of them came from Amazon (ick).
The Ladies of Uke have a lavender shirt, you've seen it in our videos. The Monday night jammers group called Dunedin Ukes have a lovely teal colored shirt, and TBUG has a different colored shirt every year. TBUS has a white shirt for volunteers, and a former black shirt for all members. MUM (making ukulele music) has the classiest shirt, I'm lucky enough to have one. The kids designed the logo. Nancy Blauers, commercial artist, designs the TBUG shirts.
Sorry I don't have any pics, but some of the shirts came from Big Frog, a pretty nice local vendor.
The only ones I think are boring are the Ladies of Uke shirts, we've worn the same color for 4 years, we'll be changing colors as soon as we can do gigs again.
I wear my ukulele related Tees out in non ukulele public, and get a lot of questions, and have met other ukers that way.
