I've never seen a picture where you didn't look great, Gary...
My "go-to" clothes are typically a business casual approach. Khakis/polo shirts or hawaiian shirts are worn for the vast majority of my routine NH gigs. I will wear walking shorts and clean, white tennis shoes on the hottest days.
Tuxedos, suits, jackets, etc. all worn when suitable.
Jeans don't work for me, nor would t-shirts, sweatshirts, etc. The attire should fit the venue and always look neat and clean.
