1961

I didn't know gypsies were known for their swimwear. From a corporate history page:

Formed by Fred Cole from family knitwear firm in Los Angeles, 1923. Company History: Began collaborating with Hollywood costume designer Margit Fellegi, 1936; signed Esther Williams to represent the company, 1950; began producing swimwear from Christian Dior, 1955; purchased by Kayser-Roth . . .

And so on and so on. Parent company went bankrupt in 01. For a while, though, their suits were known for their . . . provocative style.
