Way huge.  My regular size is XL, these were shown as 1X Big.  I called Amazon before buying to see if 1X Big was the same as XL.  Was assured it was.  But they arrived way to large to keep on comfortably.  Even the label on the pants showed XL, but I don't think so.

Something is screwed up about the sizing.

Also, the elastic is not very snug.
