Killed it when they wore Stella McCartney dresses on the red carpet. At the time, the frocks were prohibitively expensive for without a celeb-sized budget, but now, they're on sale. They're still a pretty penny, but at over 50% off, they're reasonably priced for an investment-piece. If you've got the extra dosh lying around, go for it—these are frocks you'll be able to wear for years to come. Shop at StellaMcCartney.com.
