I have come across a nice variety of Halloween costumes for your son. I was not sure which kind you wanted as there is a great variety of halloween costumes to choose from.

This Lil' Bee is a sensational soft fleece hooded cape in black and yellow with attached pom-pom antenne comes complete with matching mittens and booties. It fits Infants sizes 3-12 months. I would recommend either baby costume below. They are affordable and adorable. Will look very nice on your son and will get nice compliments.
