Dressed in a white mini dress and red stiletto heels, the actress sparked a paparazzi frenzy at the Louvre museum where the show was held, creating exactly the kind of buzz executives at Ungaro had been hoping for.

Fashion critics, however, looked aghast at Lohan's bra tops and stripper-inspired nipple pasties.

"We both love fashion, the different aspects, different generations, different styles from around the world, we like to mix everything up," Lohan told reporters backstage in a joint interview with Ungaro designer Estrella Archs.

The thigh-skimming dresses in peach, hot pink and white seemed designed for a Malibu Beach party, while sparkling nipple pasties flashing from underneath loose blazers were a reminder of Lohan's own occasional wardrobe mishaps.

"It's not good to show your nipples so they should be covered," Lohan told Reuters, referring to the heart-shaped pasties.

But her appearance was also a reminder of the risks faced by luxury brands who tie their image to that of a celebrity.

When reporters asked her about her love of scandal, Lohan frowned and snapped: "That's an unnecessary question."
