AllSaints xlarge wears like a large on me.

Beautiful shirt used but looks brand new! AllSaints was founded in 1994 by Stuart Trevor and Kait Bolongaro, who was the original womenswear designer at AllSaints and who went on to start Bolongaro Trevor. AllSaints started as a wholesale menswear brand that sold exclusively to high-end retailers such as Harvey Nichols and Harrods.[4][5][6] The company was named after Stuart Trevor's nickname, "The Saint", from his initials "ST", and All Saints Road in Notting Hill, London, where he spent much of his time.
