This is a must when wanting to be that cool girl. Look for items such as a fringe jacket it is so rock an roll and perfect with jeans or a little black dress. Or maybe you find a silk blouse with a great print, this will make you feel sexy without showing a lot of skin. You would be able to wear this with jeans as well or tucked into a high waisted pencil skirt to dress it up.
2. Try a new jean silhouette
I love my skinny jeans, but not every outfit is meant for that. Try other silhouettes such as a bell bottom. When wearing a flare leg I think its cool to make the flare the focus with an understated t-shirt, blazer and heel. Maybe add a modern statement necklace to balance the outfit out.
3. Rock edgy add ons
Ankle boots are easy to wear and can easily go from day to night. If you wear a pair that is a eye catcher you are able to turn a simple black t-shirt and jeans into an actual outfit!
