Okay, let's be real. 30 costumes, all by me, and all done out-of-pocket. So to say I built them all might be a stretch since I definitely took some short cuts and used some off-the-rack items, but I'm pretty pleased with what I accomplished. All told, I spent just shy of $415 on 30 costumes, which is about $13.78 per kid...although that figure is skewed somewhat by the three or four costumes I really splurged on. Could I have spent less? Certainly. I could have eliminated my tights order and saved over $150 right off the top, but I. Cannot. Resist. We Love Colors. (And the tights are such good quality that I only lost ONE pair out of twenty to holes and runs, and they were all worn and worn and WORN by children ages 3-11). Can I use many of these items over and over again? Absolutely. So I'm not sweating the cost (although I guess my husband might).
