I ordered this for my 6 year old for Halloween.  The costume arrived on time and it is very cute.  As previous reviewers mentioned, this costume runs *really* small.  My six year old is on the small side and I ordered a medium 8-10 for him based on another review.  I thought maybe it might be a little big and I would just pin it up and then he'd have more use out of it.  Wrong!  It fits him perfectly now.  The inseam on the "medium" pants is only 19 inches.  Luckily the waist is elastic and is approximately 16 inches unstretched.  Seems as though it could stretch to at least 24 inches without overtaxing the elastic.  All stitches appear tight in this lightweight costume.  Tag says "dry clean only" (though I will most likely machine wash on gentle cycle and let it air dry.
