Vanessa Hudgens' sultry halter dress by Diane von Furstenberg was spot-on for Global Green USA's 10th Anniversary Gorgeous & Green Gala in San Francisco.

This draped Kelly green gown will get you a similarly stunning look.

Emma Stone complemented her adorable bob with a shimmery top and skirt by Jason Wu with a tasteful thigh-high slit at the New York Film Festival.

Channel the same flapper feel day or night with this on-trend pleated midi skirt.

Emma Roberts oozed dark glamour at the Los Angeles premiere of "American Horror Story: Freak Show," in a floor-length Saint Laurent gown featuring intricate cutouts and a thigh-high slit.

We also love this pretty maxi dress that features a plunging neckline and intricate straps that play with shapes.

LBD: Check. Red lip: Check. Emmy Rossum proved less really is more at the Los Angeles premiere of "You're Not You," with a black Altuzarra cocktail dress, a flash of leg and a red mani to match her statement lip.

We also love this curve-enhancing Altuzarra dress that has a similar silhouette.

Dressing a baby bump doesn't mean you have to dial back the sex appeal. Case in point: Rosamund Pike's flowy Altuzarra dress came equipped with a thigh-high slit to add some sultriness to her "Gone Girl" premiere look in New York City.

This halter-neck maxi dress will get you a similarly body-conscious fit complete with a flirty slit.
