She briefly flashed a little more than intended on Monday afternoon while out with her daughters in New York City. But Jessica Alba ensured everything was firmly in place a few hours later, as she stepped out in a glamorous leather perforated gown at the Met Ball.

The Tory Burch-designed dress featured peek-a-boo cutouts on the chest and midriff, showing off Jessica’s figure in the process.

The actress had her brunette tresses coiled up in a bun and wore a pair of dark matching rings on her right hand to the Punk: Chaos To Couture exhibit, which examines punk rock’s influence on high fashion since its birth in the 1970s.

It was a marked contrast to earlier when the actress struggled to contain her cleavage while taking four-year-old daughter Honor and younger daughter Haven to a city park.

The Fantastic Four actress showed some side while shedding one of her outer layers, but later in the evening had everything in place in a stunning floor-length gown with peek-a-boo cutouts.

At the park, Jessica was wearing a black bra under a black tank-top with a black-and-white striped button-down shirt. She also had a longer, light blue coat that she ditched as the weather warmed up with a pair of tight blue skinny jeans and black ankle boots.

Jessica wore her long brown hair loosely and sported dark sunglasses and minimal make-up. The Sin City symbol showed her playful side and made a solo trip down the slide at a park.

She also helped little Haven with a trip down the slide. Haven wore a tan outfit with matching handkerchief and her hair was buttoned-up in a Pebbles Flinstone-style look.

Honor kept it simple in a yellow dress and a stylish grey jacket with black ankle boots. Alba has been married to Cash Warren since May 2008.

The brunette beauty is the founder of The Honest Company, which delivers eco-friendly baby-care products and household cleaners to families at affordable prices.
