Purchased this costume for my almost 5 yr old (43 inches)...got the sz M, but probably should have gone with the small (but will cut of a few inches on the bottom, so it'll be ok) I just didn't want it to be too short.

PRO: Price.  Can't beat it.

CON: -Very thin & flimsy polyester material...says on the tag that it is made in the USA....but packaging says otherwise, so not sure what the truth is.
-The WORST part: the hood/head-piece; the cut-out for the eyes are waaaaaay up in the hairline/forhead.  Will have to patch these holes and cut 2 new ones myself.
-The outfit itself looks a little "KKK'ish" so we're trying to figure out a way to fix that (maybe by writing "BOO" with markers on the costume??? We shall see)  We had a friend over that said: thank goodness the hood is not triangle shaped (referring to the KKK!) Yikes.
-The neck opening is HUGE, will have to stitch it up so it won't fall off his shoulders.

My son was OK with it, but not overly excited by any means. He has said for a couple of months now that he wanted to be a ghost....and for a pre-school party the price spoke for itself.
