Size up for more attractive fit. XL fits 160lb 57 runner carrying a few summer party pounds. (If you undersize the fabric underneath will flip up.) Attractive. Material is nice weight and feel. Nice length. Acceptable for office casual. Bust dart on one side is defective, 2x longer than other and runs 1 higher across front of chest.  Great color, very clear deep red (not a burgendy persay).
