A lord, a sleeve and a road made famous by Patrick Kavanagh (6)
I believe the answer is:
raglan
(Other definitions for raglan that I've seen before include "Br. Crimean commander; overcoat" , "coat with unique sleeves" , "Crimean commander; type of coat" , "Garment defined by its sleeves" , "A lord, a type of sleeve and a Dublin road made famous by Patrick Kavanagh" .)
