This casual combination of a tank and an a-line skirt is super easy to throw together in next to no time, helping you look awesome and ready for anything without spending too much time digging through your closet. Rounding off with a pair of black leather ankle boots is a fail-safe way to infuse a dose of elegance into your outfit. As you can see here, this outfit is a really good idea, especially for awkward fall weather, when the temperatures are starting to drop.
