I was just at our Target and they had kids' Disney rain ponchos on clearance for $3.48 (down from $4.99). They seem to fit my 8-year-old and (small) 10-year-old--well, it covers them down to just below their shorts. I also got one for my tiny 2-year-old niece but she might be swimming in it. They had princesses, Tink, Cars and Super Mario. They were on the end of the rack of girls underwear, where there are umbrellas, gloves in the winter, etc.
They are much sturdier than the dollar store ponchos.
