In the late 60’s and into the 70’s is what I normally refer to when “hippie” comes up. Not the literal definition of hippie, but the fashion side of it. Almost a psychedelic look to me.

Even though it’s in black and white, they are both wearing colorful shirts with lots of jewelry and scarfs. Men typically had longish hair during that time.

Bands like The Sylvers would usually go for a more color-coded theme type of thing. The ladies would typically wear dresses with belts and maybe hats. Men would wear “blouses” with huge collars, bell-bottom pants and visible belts. These bands and/or groups would be more coordinated.
