Dita Von Teese arrived late at her new fragrance Rouge launch event at Fred Segal.

When she was about to put on her vintage Thierry Mugler suit-dress on Saturday, Dita Von Teese found her cat Aleister contentedly napping on the designer dress.

“Slightly late to my perfume event at Fred Segal because this happened to my freshly pressed vintage Mugler suit,” the gorgeous 40-year-old tweeted to her 1.2 million followers.

The candid snap revealed the fashion culprit – her seven-year-old feline – but thankfully Devon Rexes are known for shedding less of their Poodle-style fur than regular cats.

The real-life pin-up, born Heather Renée Sweet, turned up to Fred Segal looking polished and did not appear to show any sign of the furry incident.

Dita Von Teese was her usual flawless self, impeccably dressed in the retro LBD with sheer Victorian-style ruffled neckline.

Her black-dotted sheer bodice matched perfectly with her pantyhose and she accessorized her perfume launch look with a small clutch and matching Louboutins.

Dita Von Teese’s raven hair was side-parted with big barrel curls and she sported the usual cat-eye make-up and scarlet lips on her pale complexion.

Rouge is her second fragrance after her self-titled debut, and it includes “accords of orange, bergamot, pink pepper, smoked Lapsang Souchong tea, magnolia, woody tones, and raw amber”.

The Queen of Burlesque, who once performed wearing nothing but $5 million worth of diamonds, kept her famous curves were kept under wrap.

However, Dita Von Teese tweeted her plans for performing more of her Strip Strip Hooray Shows in New York and Los Angeles soon.

In order to stay in shape, the gorgeous brunette reportedly uses her vegetarian diet and daily sessions of Pilates and sex.

The daring designer also recently launched a vintage-inspired dress and a lingerie collection called Von Follies in Australia and America.

The dancer told Refinery 29: “The dress collection is comprised of pieces that are all based on the things in my vintage collection that I believe are timeless.

“Some of the dresses are based on favorite vintage pieces that I’ve worn over and over for 12 years, and that’s a testament to a dress that transcends trends.”

Dita Von Teese, who used to be married to singer Marilyn Manson, has also dated actor Peter Sarsgaard and Mike Ness of the punk band Social Distortion.

Not seen Saturday was her last known boyfriend of three years, Count Louis-Marie De Castelbajac, a French actor and fashion designer.
