Mini dress for a big day: Shanina Shaik flaunts pert posterior in a TINY sequin slit dress as she celebrates a friend's birthday in Las Vegas

She's the Australian model who recently revealed she doesn't need chicken fillets to enhance her naturally ample bust.

And on Sunday, Shanina Shaik showed off her posterior in the mirror, and this time, there was no doubt she was all natural.

The 26-year-old took to Instagram to share a snap of the skimpy, stunning outfit she wore to her friend and fellow model Taylor Hill's birthday in Las Vegas.

Flaunt it! Shanina Shaik showed off her posterior in a skimpy, stunning sequined dress as she celebrated her friend Taylor Hill's birthday in Las Vegas on Sunday

Standing in one of the city's lavish hotel bathrooms, the model stood side-on, snapping a mirror selfie.

Shanina tilted her lithe legs to accentuate her ample derriere, while a very high seam-split in her sequined dress almost exposed her underwear.

The stunning model wore her hair straightened, as she completed her outfit with daring stiletto heels.

'Had to dress up for #tays birthday,' she wrote in the caption, referencing one of her friends.

She added the hashtags: 'vegas' and 'one night only.' 

It's a testament to the busy beauty that she continues to find time in her schedule to live it up, recently snapped enjoying the sun and sand of Antigua before heading back to her base in New York.

Once again, she took to Instagram to share a racy post of her ample assets in a blue and white crochet bikini top which she hashtagged #nochickenfillets.

Shanina has been in Antigua since Saturday shooting a campaign for Australian designer Johansen. 

The Melbourne-born beauty was due to fly out of island but had been forced to stay back on the Caribbean island following a blizzard warning in New York, according to the National Weather Service.

The Victoria's Secret model received plenty of comments from her fans complimenting her busty display as well as her bikini.

Go green in a flowing gown like Shanina Shaik

Shanina Shaik glammed up in green for an Oscars event and she's never looked better. Her gown was designed by Thai Nguyen Atelier, an Orange County, CA based brand that specializes in red carpet creations.

We adore that rich emerald hue of this dress as well as the sexy plunging neckline that showed plenty of decolletage and the thigh high slit.

The Australian beauty teamed it with some strappy Stuart Weitzman sandals as well as a bejeweled Devi Kroell clutch bag and Piaget statement necklace.

Shanina's look is custom made so it can't be duplicated. However we've selected several similar styles in the gallery below that will help you capture her essence.
