Hairstyle retro Dior fashion showcases (4)
I believe the answer is:
afro
'hairstyle' is the definition.
(type of hairstyle)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for afro that I've seen before include "Hairstyle with tight curls" , "Big curly hairdo" , "Of hair style, tightly curled and bushy" , "Hairdo of the 1960s and 70s" , "One cut" .)
