I have never heard of PianoBSharp, so I am of no help there. However, now that you have seen Betty's costumes also look at Pricilla Mooseburger's "stuff" at
www.mooseburger.com and Barbie's at
www.costumesbybarbie.com at least I think that is the address.
Now for shoes... The costumes shop I work for has a shoe that sounds similar to the clownmart shoes. I don't know for sure. It is leather, with an open toe (meaning that inside the shoe is a big open space, all your support comes from the ankle area.) I have tried these on and walked around the store a few times. For years I have worn a pair of costume built shoes by Wayne Scott at
www.clownshoesandprops.com (Wayne and his family have made shoes for Ringling since the early 70's) With the custom clown shoe a person sized shoe is made to fit your foot and then the large clown shoe is built around the inner shoe. This makes walking very natural because the stability and support are distributed around your foot. Saying that, I did get somewhat used to the open toed shoes we sell but I am now spoiled. I love my real clown shoes, I'll never go to an off the shelf model. There was a gentleman that bought a pair of the open toed shoes in a patent leather style from the store, they were bright lime green with almost a mirror finish and looked great with his outfit. They only lasted him about nine months before the leather broke through where he bent his foot when walking. Now he used his shoes quite a bit but not that much, the sole was still in good condition. He came back in and bought another pair with the natural leather finish, still green, and those have lasted him about a year now. Oh, after six years of hard use I finaly decided that it was a good idea to get new heals on my shoes and while I was at it I has a Vibram sole (that foam type material that they use on walking shoes all the time) added to the leather sole. I figure in another 10 years I may have to do it again, but I might make it to 12.
