Authentic photograph from 1979 of a young lady with a typical feathered hairstyle from that time period.
Hair is shoulder length. Bangs are relatively short and textured with layers that allow the "feathered" effect. They are rolled under with a curling iron and then brushed to the side. The sides are curled toward the back and gently directed toward the back with a brush. Only light hold hairspray was used if at all as this was before the days of the 80's when shellac-like spray was used to create a monument that didn't move. These styles were made to give the look of movement. The strands were cut in a way that they could basically fall into place.
A big cowl neck sweater in pink wool with cable knit was quite the thing. She was probably wearing San Fransisco Riding Gear jeans.
This was certainly before the heavy make-up of the decade to come.
