Should I show my barber the picture, and get this 1930s short back and sides haircut? What if I requested that I have sideburns left on (not a 1930s fashion, but I like them moderately long, almost to the bottom of the ears), instead of a tapering to the skin, at the very bottom? The hair on top is meant to be long, and the sides pretty moderately so until it tapers down to the top of the ears, so it is not the same as an undercut.
