ALESSANDRA AMBROSIO stole the show at London Fashion Week yesterday as she strutted down the catwalk in a barely-there dress.

deThe Brazilian beauty proved why she is one of the most in-demand models in the world as she made a surprise appearance in a saucy eye-catching number at Julien Macdonald’s Spring/Summer 2018 show.

kkShowcasing her talents, the Victoria’s Secret looked phenomenal in the lingerie-style dress which featured a very high-cut bodice with sheer fabric draped over.

The 36-year-old couldn’t be missed as she walked down the runway but it wasn’t just the striking garment which would have caught the attention of those sitting in the front row.

dsThe see-through fishnet neckline failed to protect the mother-of-two’s modesty as she flashed more than intended and exposed her nipples.

However, that wasn’t the only mishap Alessandra should have been worried about as her plentiful assets appeared extremely close to completely spilling out of the sexy frock.

gfThe plunging neckline on the exclusively designed CÎROC Utopia dress allowed the stunner to flaunt some serious cleavage while her long lean legs were also impossible to miss.

The cover girl posted a snap of her show-stopping appearance at event on Instagram and was immediately inundated with compliments from her 8.6million followers.

One fan gushed: “Amazing woman!!!!!!!!! The best ever!!!!!!!!!”

“This picture made my day … Gorgeous,” wrote another.

A third Instagram user said: “Most beautiful woman alive.”
