Mean to put in suits for poetry, music, etc (4,4)
I believe the answer is:
fine arts
'poetry music etc' is the definition.
(poetry and music are types of fine art)
'mean to put in suits' is the wordplay.
'mean' becomes 'near' (both can mean miserly).
'to put in' is an insertion indicator.
'suits' becomes 'fits' ('fit' can be a synonym of 'suit').
'near' inserted inside 'fits' is 'FINE ARTS'.
'for' acts as a link.
(Other definitions for fine arts that I've seen before include "paintings and poetry etc" , "sophisticate's bag" , "Creative works appealing to sense of beauty" , "Fan tries to get painting sculpture etc" , "culture" .)
