You can be so many different eras of Mike Love!
Mike Love circa-1966Beard, vintage cabbie hat, groovy 60s shirt with a not-so groovy yellow v-neck sweater on top.
Mike Love circa-1969Beard and white robe. Much simpler than the 66 outfit but requires a much longer beard.
Mike Love circa-1976Shorter but scruffier beard, bare chested sequin vest, tight white pants, some sort of big medallion necklace, and white newsboy disco hat.
