Marilyn Monroe’s costume from Gentlemen Prefer Blondes

Gentlemen Prefer Blondes, a 1953 Marilyn Monroe film, became one of the most popular pictures of the time due to her musical number in which she sings Diamonds Are a Girl's Best Friend. The actress stands out in the film not just because of her outstanding performance, but also because of her brilliant pink satin gown designed by William Travilla. The dress was auctioned off and brought in $310,000.

The dress is made of stunning pink peau d'ange silk fabric with a black silk/satin lining. The strapless gown has a straight neckline and a floor-length length. Because the garment is featured in a carefully choreographed moment, a slit in the back was made to allow for mobility. The dress also includes a huge "bow" on the back that is built into the dress rather than being tacked on separately. The bow is lined in black satin and pleated in the back on one half of the gown before folding over and attaching to the other.

Two-tone opera gloves complete the ensemble. The palm area of the gloves was made of a lighter shade of pink suede, while the rest of the gloves were made of the same shocking pink peau d'ange fabric.

Price: $310,000.
