r/petticoats

I'd like to find a petticoat which is around 80cm that also has a hemline that looks like this. It's almost impossible to find and I don't even know what to look up! Everything I find is 25 inches, me and my gf make our own circle skirts and she likes hers around 32 inches. Does anyone know where to find one? Or something custom under $100.

I was hoping to get help from more knowledgeable folk than I

Im planning on buying this dress, its 81cm total length and i was wondering what kind of petticoat to get and the length of it
