I am 6'1 and weigh 135lbs, so I was worried this size Medium would be obscenely large on me. It was not. There is even a couple ties to tighten things for that close fit look. Almost too short, but just long enough. I am impressed with the quality of the costume. It was listed as saying that the color was "as shown" which had me nervous as the others specifically said Black/Red. Thankfully the "as shown" is also black/red. The chains are also almost twice as long as shown in the picture, so they droop lower, but I like that. And finally, the red is not as deep or dark as in the picture but it IS a nice color red.
All in all this product has my seal of approval.
