Ballerina Figurines

I've had these since I can remember. They are about 4 inches tall and have highly starched tutus. The only identification are blue rectangular labels that just say JAPAN in white letters. This starched lace was probably a fad at the time they were made, whenever that was. There are many similar figurines on Google Lens. The tutus are tan colored - is this an artifact of aging or were they like that from the getgo? I was discussing this with a dealer and he said to leave them alone. If I try to clean the lace, it will take the starch out and they would be very limp and not look right.

 

Is this lace that was glued on afterwards, or actual Dresden lace, which is lace dipped in porcelain slip?

 

Glued on fabric. It is pliable, just feels stiff.
