Owl costumes are easy to makes. A long sleeve t-shirt, various colors of felt cut into U or V shapes, and fabric glue. Then glue the felt in overlapping rows until you obtain the desired mix of colors. I lack the skill to knit and only had 2 weeks before Halloween to complete this, so I bought the hat on amazon.com for less than $7. The costume came out awesome. Put together with pants and shoes that you already own. Hooray for homemade costumes that are comfortable, adorable, and less than $20.
