I recently bought a cheaper version at a halloween shop so I wanted a better quality one that wouldn't rip after the first nights use.  Sadly this one did too but it is not because of how it was manufactured.  There was no sizing chart for the item on amazon so the best I could go for was the one that amazon provides for you.  I have a 30-32 waistline and amazon recommended getting the medium.  However, when the package arrived, it said that the medium was for someone who was 5' to 5'4".  Since it was elastic and stretchy, I figured it might fit on my slender 5' 7" frame.  It fit but as I moved, it ripped a few seams.  Because of the ripped seams, I was not able to return it.  In addition, the suit gets kind of hot and its not as easy to see through as they advertise.  However, the material was a lot nicer than the cheap halloween shop and the logo on the back is not as big as other reviews make it seem.  All and all I would have enjoyed this product had I been properly informed of the correct size to get.
