Chasing girls, primarily, the Parisian pulls - but they're worn out (4,4)
I believe the answer is:
glad rags
'they're worn out' is the definition.
The definition suggests an adverb but the answer is not.
'chasing girls primarily the parisian pulls' is the wordplay.
'chasing' says to put letters next to each other (some letters chase after others).
'primarily' says to take the initial letters.
'the parisian' becomes 'la' (French for the).
'pulls' becomes 'drags' (drag is a kind of pull).
The initial letter of 'girls' is 'g'.
'g' next to 'la' is 'gla'.
'gla'+'drags'='GLAD RAGS'
'but' acts as a link.
Can you help me to learn more?
(Other definitions for glad rags that I've seen before include "Smart clothes (for a special occasion)" , "best suit" , "Dressy clothes - happy threads" , "Special kit" , "What partygoers showed up in" .)
