Yes and no...
From the ground up it will be every time Black Hiking Boots, Faded dark blue Carpenter Jeans and the required underlayment, some sort of shirt. I am a big dude, so I tend to wear a LOT of black on stage. Black polo shirt, black T shirt, black long sleeve dress shirt, or almost black / charcoal, weather dependent sunglasses or not, and a black 10 gallon felt hat.
Having said that, I am in a trio of hacks and we are sort of standardized on our look / presentation. Black high tops or boots, dark but faded jeans, some sort of black or charcoal shirt, and a black or charcoal hat.
So for example, I play with 2 guitarists, a lead, and a rhythm guitar. (Drums are from synth for now, looking for a drummer that will put up with us is a pain).
Lead Guitar. Black All Stars, dark blue Levis, Black long sleeve dress shirt with charcoal pinstripes, black wraparound sunglasses, and black Fedora. Rhythm guitar, Black Addidas I think they are, Dark blue jeans, probably Walmart specials of some flavor, Black long sleeve "Fishing" shirt, and black straw 10 gallon hat. Me, Black Wolverine hikers, dark blue carpenters, Black long sleeve shirt and black felt 10 gallon hat.
