The other site I visited was the kicker for fun underwear. What Katie Did. There is a UK and a US link. If I ever get rich and well, rich, I'd love to get my hands on one of these creations. (on an aside, am pretty sure 'What Katie Did' was also a book....) I probably could sew something akin to these. Yet, it is hard to do fittings when the person sewing is the one being fitted!
Enjoy this foray into the underworld of fun fashions!
