There's balance shown in this outfit between the simple white tank top and the layered full skirt. The common white background allows them to match while the pattern and texture of the skirt makes it focal piece of the outfit.
Use stripes to your advantage with an oval body type. These stripes draw attention up with an empire waist and v-neck. A great fitting blazer will create a long lean line when worn open over the top. The light washed boot cut jeans also help balance and draw attention away from the mid-section.
