Jack The Ripper Costume. "Jack the Ripper" is the name given to an unidentified murderer who was active in the largely impoverished areas around London in 1888. Our Jack The Ripper Costume perfectly replicates how London men from the late 1880s used to dress, as the outfit comes complete with a double-breasted vest with burgundy trim, a cloak, jabot, and hat. This sleek black costume is versatile as it can be worn for any costume party or Halloween yet to come.
