The Feather Shop
Along Ylaya Street located in Pasilio-W
Does Custom Costumes. Also has ready made costumes for sale, mostly stuffed toy snakes, feather wings, dozens of assorted headgears ranging from Eqyptian Pharoes to Cocacobana Stage Dancers. Last checked they were selling almost complete (although inaccurate) Encantadia and Mulawin costumes.
