I am a 42 year old struggling a little on an image these days as the type of clothes that are in style for young bands seems very off for me. The wrinkly, cheap sport coats and british influenced garb doesn't look very good on me, imo. I promise not to copy what you wear but would you show a pic of how you dress ?
I'll see if I can find a photo, but in the meantime I can give a quick description:
Shoes: Boots or sneakers, depending on the season. White sneakers tend to pop out; black tends to fade into the background.
Pants: Camouflage paratrooper pants; I've got them in several colors, in patterns with large areas of color so they won't blend too much when seen from a distance (the modern "digital" pattern doesn't work well; in this application it's really "anti-camouflage", intended to stand out rather than blend in).
Shirt: Anything goes,
except a match to the pants! Solid color (including white) T-shirt, tie-dyed T-shirt, or Hawaiian print shirt in a color that clashes with the pants. If I'm playing a ski resort, etc. I'll wear one of their shirts sometimes, if I can get one.
Jacket: Black or white sport coat.
Hat: None (I'm not really a "hat guy", plus I don't like having my face in shadow).
Other accessories: Generally nothing else, like shades, scarf, tie, etc. unless it's a tie-in to the event or season (like Mardi Gras beads, etc.).
In a way, it's almost clownish with nothing really "matching" in any traditional sense. But it stands out, gets people interested & talking. At the same time, I'm not really wearing what's "in" for 20-somethings, which tends to look pathetic when older guys do it (I'm older than you are). Plus it's just plain fun! Looking fun & acting fun tends to rub off on other people, & when the people around me have fun I tend to get asked back more often.
I don't mind if somebody wants to use some, or any of it. It's nothing secret, & I'd probably be flattered if somebody wanted to copy my look! It's evolved over a long period of time, & there's really nothing I'd wear onstage that I wouldn't wear around town shopping, etc. (just not in the same combinations). I take my look seriously in the sense that it's planned & part of a strategy to stand out, not just what I happened to throw on today, but I don't take
myself seriously in the sense that there's any great importance to myself or any of it. It's all part of the show, there to entertain & amuse people.
