Nicole Trunfio struggles to stay in a strapless dress

Still spilling out! Now Nicole Trunfio struggles to stay in a strapless dress as she heads to a Fashion Week show with fiancé Gary Clark, Jr.

She had her cleavage on show earlier in the day when she went to breakfast in a busty exercise top.

And Nicole Trunfio was still spilling out of her attire when she headed to a Fashion Week show with fiancé, Gary Clark, Jr. later on Tuesday.

The 29-year-old donned a VERY low cut white strapless dress for the outing on day two of Mercedes-Benz Fashion Week, as the pair left their newborn baby at home for the day.

The Italian-Australian model played to her diminutive waist in the delicate floral print frock that flared from the waist, giving her the illusion of an hourglass figure.

Nicole, who gave birth to the couple's son in January, looked radiant as she strode along holding the hand of her husband-to-be.

With her undeniable sex appeal, the brunette oozed Marilyn Monroe-style glamour, her caramel locks tamed into a sleek middle part and styled into a low slung ponytail.

Her dewy skin was offset by a dash of show-stopping red lipstick and her cheekbones given extra drama with bronze brush strokes.

Wearing simple stud earrings, a pair of chunky black shades and a classic Chanel handbag, the Pirelli pin-up girl showed her innate sartorial style.

The five foot ten inch catwalk queen added even more inches with a pair of nude pumps, but still her boyfriend towered above her.

Accompanied by her Grammy award-winning beau, the musician encapsulated offbeat bluesy style in loose fit black trousers, a suit jacket, a white shirt and a pair of buckled boots.

The couple made their way to Carriageworks where designers are exhibiting their SS15 collections and attended the star-studded Toni Maticevski show together.

Seated in the front row, the couple mingled among the A-List crowd around them, including Nicole's good friend Gemma Ward, who was with the couple in Byron Bay for Bluesfest last weekend.

Perth-born and raised Nicole has sprung back to her model shape with enviable speed since giving birth in late January.

Earlier on Tuesday the toned, trim model gallivanted around Sydney's beach suburb Bondi in an incredibly small exercise top that did little to conceal her assets.

Meeting a friend for brunch at local spot Bill's, the lean cover girl continued to flaunt her famed figure in a pair of low sitting leggings that showed off her washboard abs.

Confidence has never appeared to be an issue for Nicole, who is used to stripping down to lacy negligee for racy fashion shots.

The statuesque beauty has been Down Under since the beginning of April – it's believed it's the new parents' first visit to Nicole's home country since she gave birth.

The IMG-repped model has been supporting Gary while he played at Byron Bay's Bluesfest and a series of gigs throughout Australia.
