The Mad Men star is known for her liberal approach to flaunting her famous curves on the red carpet.

However Christina Hendricks chose a more modest look than usual for the Iris: A Journey Through the World of Cinema premiere in Hollywood yesterday.

The stars understated ensemble covered up her ample cleavage, which normally draws avid attention at such events.

Meanwhile High School musical songstress Vanessa Hudgens strayed from her normal PG appearance, flashing rather more skin than she may have planned.

Spot the difference: Both Christina Hendricks and Vanessa Hudgens both donned prints for their Cirque Du Soleil appearances in Hollywood yesterday, but Vanessa’s daring choice led to her flashing more skin than usual

36–year-old Christina looked sweet in her leopard print dress, which was a far cry from raunchy ensembles she is often seen in.

The actress’s neckline was high, and the dress’s puffed sleeves minimised the effect of her generous bust.

The outfit was fitted but not skin tight, and there didn’t appear to be any danger that the star’s ample curves would spill out.

Letting something slip? A wardrobe malfunction meant that from the side cameras nearly caught a full view of the 22-year-old

Understated: Christina covered up her curves with a high neckline, choosing medium height heels and avoiding her sometimes skin-tight usual look

Discreet but effective: Christina chose neutral black for her clutch and shoes, wearing amber earrings to blend with her hair colour

Christina chose medium height black heels for the appearance, not risking a red carpet tumble in stilettos.

She was accompanied by her husband Body of Proof star Geoffrey Arend, and the pair beamed side by side, Geoffrey not seeming to mind his wife’s discreet attire in the slightest.

The actor himself looked smart in a green suit jacket, checked shirt and black trousers combination.

Sultry: From the front Vanessa looked sexy and sophisticated, although rather more was on show from other angles

Vanessa on the other hand opted for a sexier look, with a plunging neckline on her loose-fitting full-length dress making it clear that she wasn’t wearing a bra.

A large silver pendant drew further focus to her exposed chest, which was evenly tanned thanks to her Hawaii holiday earlier this month.

Elegant: Christina’s unusually discreet dress did nothing to detract from her gorgeous looks, with soft makeup accentuating her natural beauty

At one point however the 22-year-old’s decolletage was on dangerously close to full display, when the side view of her dress gave a rather too generous generous view.

90210 starlet AnnaLynne McCord appeared to have been gunning for a part in the latest Cirque du Soleil reincarnation, looking like a sexy circus gypsy.

Stepping out without present boyfriend Dominic Purcell, the 24-year-old actress showed a flashed of her perfectly toned figure in the ensemble at Kodak Theatre in Los Angeles.

Although her skin-tight floor-length camel-coloured skirt clung in all the right places, it was her top that showed the most skin.

She showed off her toned tummy in what was essentially a purple lace bra but managed to retain some modesty with a green wrap.

The actress accessorised with a Cirque-friendly sun pendant, a slew of studded orange bracelets and tan heels.

Several other big-name stars joined McCord on the red carpet to catch the show, which can be described as a mixture of circus arts and street entertainment.

Kate Beckinsdale, 38, made a beeline inside the theatre looking far more laid back than many of the ladies in skinny jeans and a blazer.

Other celebrity attendees included: Matthew McConaughey and partner Camila Alves, Anne Heche, Grey’s Anatomy star Patrick Dempsey, model Cindy Crawford and Neil Patrick Harris.

Iris takes a unique look at the history of cinema and weaves in Cirque de Soleil’s unique blend of dance, acrobatics and modern circus traditions.

The name of the show, Iris, is taken directly from both camera diaphragms as well as the colored iris of the human eye.

The production cost $120,000 to make and is scheduled to run in Los Angeles for ten years.

It began previews on July 21, which explains why some celebrities such as Twilight star Taylor Lautner, have already seen the show.
