History of Famous Jewels and Collections: Re: Marianne Ostier as a designer

I don't know, if the system used for cheap costume jewellery half a year later was indeed the same, but Marianne Ostier seemed to have thought it was too close to her own device and threatened legal action.

Life Magazine, 16 April 1951 referred to that incident and described the method on page 125:

Tempest in Tinsel Trade

Pins that stick to bare skin stir up fashion and legal fuss

Last week department stores unveiled some scatter pins that adhere to the skin without any visible means of support, and the jewelry trade sat back to await the results. They promise to be interesting from a legal as well as a fashion point of view. Variously called Skin Pins, Cling Pins or Magic Pins, the new jewelry is a variation of the old college girl trick of Scotch-taping an orchid to a bare shoulder above a strapless dress.

Last fall a designer of expensive jewelry, named Marianne Ostier, announced a secret process that glues diamonds on a sponge base safely to the skin. At diamond prices her jewelry aroused little popular interest. Then the news got around that some costume-jewelry makers had dreamed up their own adhesive methods. Mrs. Ostier took a Woman's Wear ad to threaten legal action against unlicensed users of her device. But the new pins came out anyway, and buyer interest (at prices from $1 to $10) was lively. The baubles, in star, sunburst, butterfly and heart shapes, are sold with tubes of stickum, which is applied to their flat metal base and allowed to dry several minutes. The pin is clamped firmly to the skin, where it stays put until pulled off, a painless operation. The placement possibilities of the tinsel are numerous. They can be worn Hindu-fashion on the forehead, as earrings, on the ankle and anywhere on the shoulder area.
