Lindsay Lohan cuts a voluptuous figure in a plunging dress as she supports sister Ali at New York Fashion Week

She bailed on the Venice Film Festival to stay home and concentrate on her health.

But one thing Lindsay Lohan couldn’t miss was seeing her model sister Ali strut down the cat walk in Wendy Nichol’s Fall 2013 fashion show in New York City on Wednesday.

Although noticeably more fuller figured than when she left rehab, the 27-year-old actress embraced her new curves in a daring outfit choice.

Lohan arrived in a fitted, plunging black gown to view the designer’s Ready-To-Wear collection at the Elizabeth Street sculpture gardens.

The bodice of the dress hugged her body, giving the illusion of an extremely short mini dress, as a layer of chiffon flowed above to conceal her legs.

Seeming to somewhat blend in with her sister, the Mean Girls star sported a gold head piece as she allowed her red locks to lay in loose curls.

Yet, it must have been a steamy day in the city, because LiLo later styled her tresses into a low bun, allowing her skin to breathe a bit more.
