At last, Megan Fox’s red-carpet style is officially back in business.

The actor looked like a knockout while attending a Sports Illustrated Swimsuit launch party in New York City last week. The event marked one of the first times she and fiancé Machine Gun Kelly have been spotted in public together since rumors of a split emerged earlier this year.

For the flashy occasion, Fox wore a jaw-dropping black gown by LaQuan Smith. The piece featured a see-through mesh long-sleeve bodice with black panel cuffs on the arms and a plunging scooped neckline. It also included a shiny black sheath skirt with a subtle train. She let the dress do most of the talking, eschewing flashy jewelry and instead wearing a single chunky silver ring. She capped off the look with a pair of black platform-heeled sandals.
