For example, if you need your hoodie, wear it with a matching skirt, a pair of tights, and boots. Ankle boots, combat boots, knee length boot, or rain boots work. Add some flare with stud earrings, a purse, and/or a bracelet. Keeping casual items in the same general color scheme really ties together unity and neatness for the outfit.
The outfit below is a something that I created this weekend. I needed to make a quick run to a few stores and wanted easy sophistication. My gray crop top paired with another shade of gray of yoga pants and black ankle booties gave me exactly what I was looking for! Adding my everyday cubic zirconia studs, faux diamond bracelet, and shades helped create some attitude.
