I've learned super-hero costuming is year round apparel in our house.  Last year's Blue Batman and Baby Robin costumes were designed with time (to complete) and cost (think cheap) in mind.  I expected they'd only be worn for Halloween - which was true for my growing baby boy, but Elijah's worn his out.  For this year's costumes I'm focusing on functionality and durability with less emphasis on how long and how much.
