You might not say it is a simple attire, with dress and semi-high heels, but the truth is I have not make-up on, just shades, and I did not even brush my hair before going outside to start the bbq.
Dresses with drapes are flattering for bodies with a bit of pear or hourglass shape. Choose the ones that are about knee-length, and let it stop at the narrowest part of your calf or knee area. This way you elongate your legs.
On this one, you can replace the belt also, wich will give it a totally different look every time you use it:)
