Query: Sad Superman

I bought this costume for my 3 year old son's Halloween. I left it in the package in the box so that NOTHING could happen to it before it was time to wear it. I should have pulled it out and at least looked at it. That was my mistake. When I took it out of the package as we were getting ready the back had runs in the nylon around the behind area and the stitching that held the top and bottom halves together had come apart in the back. It was awful. What a waste of money.
