From Lip Service's site:

Lip Service Institutionalized Twill Straight Jacket.  Tie me up or tie me down this classic is always noticed at the club.  You'll be the star of the show in your very own padded room in our updated Straight Jacket with a front zipper closure, five nickel plated locks(keys included, don't lose them otherwise you're sleeping in it ;), convertible sleeves that can be unhooked and extended to actually restrain you in straight jacket fashion.  It's a fitted jacket so it runs slim for ultimate style and constriction.
