Blake Lively has put a Valentine’s Day twist on her already showstopping style.

The 29-year-old wore a flirty, silk, heart-print SemSem dress with sequins on Monday at the L’Oreal Paris Paints + Colorista launch event in New York City as she celebrated Galentine’s Day with her sister Robyn Lively and her mom Elaine at her side.

The actress was all smiles as she showed off her toned legs in the silk chiffon mini that featured white and red hearts, a high collar and flare sleeves. She uploaded a photo of her stunning studded Christian Louboutin footwear to Instagram, writing, “Happy Galentines Day.”

In true Lively fashion, the actress’s hair was styled in a heart shape plait at the back to match her outfit.

At the event, which Blake hosted and helped plan, she jokingly compared the soirée to a birthday party, saying, “Thank you for coming to my super sweet 16!” she said.

The actress decorated cookies, made Valentine’s Day cards and mingled with guests throughout the night. She even left a special message on a large wall at the party, writing, “I’m worth … my rights, equality, love, respect, kindness, opportunity, inclusion, more sleep, chocolate.”
