The long hair and hippie clothing is 1968.
Here's the Everlys in the 50's:
The Everly Brothers’ Phil and Don Everly pose for a portrait at the Victoria Palace Theatre in London circa 1958.
I have no idea about the clothing all I have is what is in the photo and here is what they claim.

Totally!! :-)
The Everly Brothers’ harmonies GREATLY influenced George Martin to do the same with a couple of newly signed band members by the name of John & Paul.
That is NOT 1958, look at the hair...look at the clothes...1968, yeah Id buy that but no one looked like that in 1958.
