In The Age of Adaline, Blake Lively plays a woman who never ages beyond 29—and it looks as though the same can be said about her in real life.

At an event to promote her new film, Lively truly looked forever young. The star was absolutely radiant in a flirty '60s-inspired cut-out Lindsey Thornburg dress (an exclusive to her lifestyle site Preserve and available for $425) with spring-happy blooms in a color palette of purple, pink, and yellow. The finishing touches? Sunny strappy mules to complement the dress's yellow accents, and tumbling half-down waves.

The Age of Adaline doesn't hit theaters until April 24, but in the meantime, we're keeping our eyes peeled for more instances of her youthful beauty.
