found all the costumes at party city back in july for $5 each.
kellen's was a 12-18 month size and a bit snug.
christian's was a big boy's medium and well, he'll be able to wear it years to come;).
and the girls were swimming in the leggings, so we replaced them with tights.
but overall, not a bad deal.
