Tuxedo Style?

Back in highschool, for prom I rented this jet black tuxedo. The jacket was a 3/4 length jacket with one button right up by the neck and the rest of it was open. Now, many years later, I'm trying to find that same style and can't remember what it was called. Also a friend wore a similar jacket that buttoned down the right side of the coat and i believe was a 3/4 lenght jacket also. Anyone know what these are called or know of a site that sells them?
