Did you know that Zac Posen has designed a Barbie and Ken doll gift set? Yeah, neither did we. "Inspired by the designer's own Tribeca studio; his dog Tina; and his muse, sister, and creative partner, Alexandra." Much like his clothing, we wouldn't be able to afford Zac Posen's Barbie either. It's $274.99! Anyway, Zac joins the likes of Anna Sui, Givenchy, and Escada—all designers with "signature" Barbies. [BryanBoy]
