When the Playboy Bunny suit made its club debut on February 29, 1960 in Chicago, it was missing a few notable elements that have come to be an expected part of the outfit—namely, the tuxedo collar and cuffs and the name-tage rosette. Besides those key addtions—and the notable subtraction of fabric via a higher-cut leg line—the world-famous costume has remained remarkably stable across the decades. Tribute, we think, to how great it was to begin with.

Here are the essential elements of the sexiest work uniform in the world:

SATIN EARS

Worn crooked or straight, the Bunny ears offer the wearer a form of subtle self-expression.

BLACK BOWTIE

The Playboy Bunny’s delicate balance of playfulness and sophistication starts here.

BESPOKE SUIT

Custom-made and hand-tailored to each and every Playboy Bunny, the suit creates a silhouette recognizable from a mile off.

PLAYBOY CUFFLINKS

Bunnies ensure that the little silver Rabbit Heads on their cufflinks face each other, or “kiss.”

ROSETTE NAME TAG

The individualized nameplate is worn on the hip, which is eye-level for seated customers—learning names has never been such a pleasure.

FLUFFY TAIL

The final touch to complete the costume, the tail sits centered at the small of the Bunny’s back.

CRISP WHITE CUFFS

Added, along with the bowtie and collar, in 1961, the cuffs caused the world to ask, “Who needs sleeves?”

NUDE + BLACK TIGHTS

The early Bunnies doubled up, layering black pantyhose over nude tights.

STILETTO PUMPS

Bunny pumps historically match the color of the suit but today are commonly worn in black.
