Layering Outfits
Layering is basically a way to style a look by wearing many articles of clothing on top of each other.
Why
Layering has almost no function unless it is cold outside, but it sure does look appealing. When you layer outfits there is a contrast in the texture, shape, and fit of your look. It is an easy way to elevate your appearance and add new proportions in order to create a new silhouette.
