Traditional in style, Afros like Sly's regularly picked (6)
I believe the answer is:
trendy
'traditional in' is the definition.
'trendy' can be an answer for 'in' ('in' can mean trendy or fashionable). I'm unsure of the 'traditional' bit.
'style afros like sly's regularly picked' is the wordplay.
I cannot really see how this works, but
'style' could be 'trend' (synonyms) and 'trend' is present in the answer.
'like' could be 'y' (similar in meaning) and 'y' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for trendy that I've seen before include "Modish" , "In accordance with the latest fad" , "Informally in the latest fashion" , "With-it" , "Informally fashionable" .)
