When it comes to Paris Hilton it looks like the older you get the less clothing you wear. The socialite who celebrated her 33rd birthday over the weekend almost turned her embarrassing wardrobe malfunction into a humiliating one.

According to E! News, the DJ headed to West Hollywood's Greystone Manor on Saturday for an extravagant bash but opted to go without her underwear.

This may have not been the best choice seeing as the heiress wore a hot pink Alon Livne dress, which featured a thigh-high slit and a flame-inspired bodice.

While the ensemble flaunted the blonde's long legs it also exposed her tan lines as her skirt opened up several times while on the red carpet. At times the starlet flashed her butt check and part of her vagina, she also posted a topless photo on Instagram.

Even though the dress showed a lot of skin Paris Hilton loved it. She told Us Weekly, "This was one of the couture gowns [from the runway], and I said, 'I have to wear that for my birthday it's like the perfect Barbie princess dress.'"

The "Good Times" singer took to Instagram to give props to Livne and called him, "such a talented & creative designer!"

The former "Simple Life" will be celebrating her birthday for "about a month," and has already hit hotspots in New York City and Miami. Next up, Hilton has plans to make her way to Brazil and Las Vegas.

For her 21st birthday in 2002 the party girl managed to throw five events around the world.

The heiress took to her Twitter account to thank all of her followers for their well wishes. She wrote, "Thank you all for the birthday wishes & for making me feel so special on my birthday! You all mean so much to me! Love you all!"
