17.5 in. (chest)
26.5 in. (length)
I have two of them, one in green and one in navy. They're slightly big on me. I'm 5' 6'', 127 lb., about 34 chest. So I think they will fit best on someone with 36 chest, probably around 5' 8'' or 5' 9''. I bought both from J. Crew. I cut the tag off on the navy one thinking I'll keep them, but otherwise, they're both new.
