We have had Adam's old Spiderman costume floating around for years, and believe me, we've gotten our money's worth.  Adam was Spiderman for about three Halloweens, and now Lukie has decided it is his go-to lounge-around outfit.  He changes into it every afternoon after school and insists on wearing it to bed.  It is rather the worse for wear--there are huge holes in the sides and crotch seams--but hey, if it doesn't bother him, why should it bother me?
