It's gonna be that outfit with red overalls, white top and long legged light blue sandals. Of course that lovely green wig and red contact lenses to finish the exact look ^-^

Update 1. May 2015

I've made the basic patterns for the overalls and next step is to modify them to look more like Ranka's. I've got the fabric for them and contact lenses are on they way from Youknowit.com (I highly recommend their web store!). Today I'll check out if I can find shoes from second hand stores for this costume, wish me luck! :)
