My son is 8 years old and he loves this costume.  It fits him perfectly and he's a dead ringer for Harry Potter!  The glasses are an exact replica, something my son has begged for; and the wand is plastic, nice and sturdy.  The robe is 100% polyester, thin, lightweight and not too shabby.  I don't see loose threads or seems coming apart.  It looks like it will last through all his spells and incantations.

The only thing my son thinks is missing is a Gryffindor tie.  We'll have to go buy that.  Great costume!
