The lady is a vamp! Katie Holmes unleashes her sexy side as she flashes flat stomach and sideboob at Women In Gold premiere

Katie Holmes stood out from a crowd of black ensembles as she unleashed her sexy side at the Woman In Gold premiere in New York City on Monday.

For the red carpet event at the Museum Of Modern Art, the 36-year-old actress donned a Zac Posen Fall-Winter 2015 Bugle-Bead Cocktail Dress with cutout detailing showing off her toned midriff and a bit of sideboob through the center cut-out detailing.

The single mother-of-one looked stunning as she lead a bevy of A-list beauties including Brooke Shields and the film's leading lady Dame Helen Mirren.

Katie was styled in a sleeveless patterned frock that was adorned with embroidered floral prints all throughout.

The ex-wife of actor Tom Cruise drew attention to her impressive abs even displaying seductive sideboob.

She accentuated her long legs with a pair of black high heels and rounded out her look with two delicate bracelets.

The star was accompanied by designer Zac Posen, who dressed dapper in a grey suit and trousers with orange knitted sweater.

Be a cut above the rest in a Zac Posen like Katie Holmes

For the Women in Gold premiere in New York, Katie Holmes left the mom jeans and sneakers at home and opted for a racy look by Zac Posen.

The stunning creation featured cut outs along the side and back with floral embroidered fabric. Teamed with a pair of black pointy toe pumps, this was a perfect red carpet ensemble.

Katie's dress was ripped from Zac Posen's Fall 2015 runway which included lush colored furs, shiny metallics, and plenty of form fitting silhouettes, perfect for the designer's elite clientele.

You can't get this number in stores just yet, but the flirty frocks in our edit are yours for the picking. May we suggest River Island's ultra feminine botanic and check print pencil dress? It's only $60 but you'll look like you spent a lot more and it nails this season's major trends just right.
