Go round appearing as Romeo in a sketch (5)
I believe the answer is:
skirt
'go round' is the definition.
(I've seen this before)
'romeo in a sketch' is the wordplay.
'romeo' becomes 'r' (phonetic alphabet: alpha, bravo, charlie etc.).
'in' indicates putting letters inside.
'a sketch' becomes 'skit' (short comedy performance).
'r' put within 'skit' is 'SKIRT'.
'appearing as' acts as a link.
(Other definitions for skirt that I've seen before include "Garment below the waist" , "Go round; garment" , "Female garment" , "Go round the edges of" , "Go along the edge of" .)
