AMy money is on the creator casting the molds themselves for the event.
i would get something like this and make a mold-- i hope the porousness of the skirt doesn't mess up the mold making--but this particular piece has a few dings so it's probably not gonna get too pricey-- something like this and make a mold -- maybe
but i am irritated because i know i have seen molds like this before in years past and i can't find them now...a cameo mold might work
ALooks like Rosalind ****** did the ones pictured from the OP. For the mentioned event im sure they had access to original figurines to make these. I did find this mold online http://www.ebay.com/itm/Antoinette-Half-Doll-Mold-Plaster-Mold-Made-To-Cast-Porcelain-Or-Ceramic-/221236161121 But I don't think it will work for you. I seem to agree with post above that I have seen sucker molds with Madame pompadour /Marie Antoinette style, but don't see it on searches now. I've seen enough creepy dolls. No more searching for me...... ..good luck..show us what you come up with!
Edit--- really unsure of the censorship?????
Oh thank you everyone, certainly some food for thought! I've traced them back to cupcakes made by Rosalind ****** so I'm guessing they have access to some amazing tools. I, too was sure I'd seen a mould in the past but as always, when you want something you can't find it!
I'll post if I come up with anything :)
Thank you :) This is a good possibility!
maybe too small--the right idea maybe not quite right though
and another --probably a miss-- i can't even tell what kind of mold it is and it's only fifty five dollars
AThat topper looks a lot like the ceramic figurine with the skirt made of buttercream. Made in a similar style as the Barbie doll cakes.
I agree with AZ Couture. It looks like Cake Opera Co. to me. I'd check with this person. I bought some of the Marie Antoinette style molds and they are high quality. Not the same as what you're looking for, but they do custom orders and might be able to help. Good luck!
