Chloe Moretz just turned 15 on Feb. 10, so it's fitting that she would be the one to show us that subtle sexiness is way more fashion forward than anything overt. The adorable actress attended an event in Hollywood clad in an all-black outfit that's easy to re-create when you're not feeling too colorful. Start with a simple black lace tee, which plays a little game of peekaboo on the eyes. Then, like Chloe, complete your classy-cum-sexy look with black skinny pants or jeans, cutout booties, and gold jewelry. But don't go overboard with the baubles because the outfit will look too trendy. Chloe chose a spiked pyramid ring and a long necklace. Wear a camisole underneath the lace tee for coverage during the day, then take it off to reveal a pretty bra for night. Simple, classy, and sexy all at the same time. That deserves applause.
