Double Murder

I was in a gents outfitters getting measured up for a new suit.
The material was a violently bright beige check, although the pattern was quite small.
Harris Tweed, of course.
The jacket seemed to be around XXXL but fitted nicely.
I turned around and two men, one in a red suit were sniggering at me.
I therefore found a steel bar and murdered them both.
Very violent and gory.
Then I hit the High Street with my Harris Tweed suit, complete now with red spots.
