More Teen Halloween costumes than ever. Buy teen boys superheroes, or teen girls costumes styled after sexy adult costumes, but with more coverage. That awkward age between 'child' and 'adult' doesn't have to be so bad when you shop for Halloween; the costuming industry has begun to create outfits in varying, specific sizes from infants to plus size - and they remembered to include those in-betweens, in scary and sophisticated styles to match the preferences of their audience. There is also a larger selection of smaller mens sizes, making another option for young men.
