Wearing the same size as your sister doesn't mean doubling your wardrobe for Solange Knowles. The singer tells Vogue (via Us Weekly) that she "never borrowed clothes from Beyoncé when we were growing up." She adds, "my style is a little more tame, and hers is a little more adventurous."

Still, Solange is supportive of her sister's signature style. "I love seeing her with an hourglass silhouette," she tells the fashion bible, admitting that she even checks blogs to keep up with Bey's vacation outfits.

She points out a polka-dotted Marc Jacobs outfit a pregnant Bey wore on a recent trip to Paris, saying it was "like something Jackie O might have worn, but when Beyoncé wears it, it's transformed."

Clearly, there's no cause for sibling rivalry when beauty and style run in the family!
