Last night at the VH1 Do Something Awards, Olivia Wilde wowed the blue carpet in an ultrafeminine pale green flowy keyhole dress. I love this style on the svelte actress and think she looks both comfortable and glamorous. Keyhole cutouts are a subtle way to show off skin without revealing too much. The only challenge is finding the right undergarments (sticky chicken cutlet silicone pasties are a must) to pull off this look. Below are even more fashion-forward keyhole pieces for Fall for you to shop. Have fun, and let me know which items you like best!
