When we first saw this photo of Sienna, we were in love with her necklace, but then after a few more looks, we realized that is actually part of her Pucci dress! From the line’s Spring 2007 collection, this dress is actually a taste of what’s to come in fashion this spring. Soon, you’ll be hearing a lot about “Futurism” as the new theme in fashion — from Sienna’s metallic “neckpiece” to the robot-like gold armored leggings from Balenciaga (for a cool $20,000, no less), metal is the hot motif for spring. Once again, we can count on Sienna to set the trends (although everyone else can feel free to keep their pants on). Now, we want to know when the weather will warm up enough to start wearing spring clothes?
Check out all the latest trends and star style in the new issue of PEOPLE Stylewatch, on newstands now.
