It's a blossoming fashion battle!
Both Rihanna and Liv Tyler were spotted in Givenchy's oversize satin tee from the label's 2012 resort collection.
Ri-Ri, 24, went casual street chic in New York City by rocking it with blue jeans, Alexander Wang black lace-up boots, a chunky gold-link necklace and her blond hair pulled up in a bandana.
Steven Tyler's 34-year-old celebuspawn and Givenchy spokesmodel went for a flirtier, more polished look by pairing her top with a pencil skirt, blazer and lovely black strappy heels as she headed to a Givenchy commercial shoot at Place Vendôme in Paris.
So which beauty shuts it down in the floral topper?
