My daughter begged for this Halloween costume and really likes it - so even though its a little small and will require some sewing work - there will be no returning it.  In terms of sizing, the costume runs small.  For example, the 3T/4T size is really more of a 3T. The jumpsuit part of the costume is well made.  However, the feathery trim is only stitched on in a few places - so if you want it to stay on to endure the extra playful kitty, you will have to be prepared to do a little extra stitching.  Even with these issues, it does look as cute on as it does in the picture.
