I have made almost all my family's Halloween costumes. I think they cost about the same as store bought unless you buy the super cheap kinds. However, I think they look better than any store bought costume. Also, my family likes to pick a theme and we all go as a character in the theme. Last year, we went as the Wizard of Oz with The WWW, Toto, Dorothy and the Scarecrow. This year, we've been talking about going as Alice in Wonderland, but no one wants to be Alice and both girls want to be the chestercat. If saving money is the goal, then it probably costs more to about the same as a middle of the road costume. However, homemade costumes usually look more expensive than they are. Also, adult costumes can be used year after year.
