Marian Uhlman[1] (née Sorenson; December 16, 1921 – October 17, 2003), known as Chili Williams or the Polka Dot Girl, was an American pin-up model and actress.

[1] After graduating from high school, she worked as a stenographer and model for a fur store in Saint Paul, Minnesota.

[3] In June 1943, Marian Sorenson moved to New York City and joined Harry Conover's modeling agency.

Life published the photograph in its September 27, 1943, issue, along with Conover's letter stating: "This picture shows Miss Chili Williams, my newest Cover Girl ...

"[7] Syndicated newspaper columnist Earl Wilson wrote in December 1943 that "the picture that caused all this rumpus" showed Williams "popping prominently out of a pair of polka dot bathing pants and a form-fitting polka dot bra.

"[4] He joked that the editors of Life "hate cheesecake like poison", but bowed to the demand for more Chili Williams.

[9] During the height of her popularity in late 1943, Williams was seen dining regularly with South American playboy and billionaire Jorge Guinle.

[4] In 1944, the Army Engineers hired Williams to pose for a series of photographs to be used for training lectures on the use of camouflage.

[10] The Army stated in an official release that, by using images of Williams, "vital principles are impressed in the minds of camouflage students in a most effective manner.

[11] In 1948, Williams was the grand marshal of a parade in San Mateo, California, while riding on a polka-dotted horse.
