Don't Even Bother
Starting with my oversized cartoon tee I decided to build off of that theme. While looking through my closet I noticed my ZARA Mermaid skirt's pattern almost looked like cartoon scribbles which is how I knew to match it with my graphic tee. Since my skirt is structured it also gives shape to my oversized tee.
Of course, with any whimsical themed outfit add a pop of color. It helps make your outfit even more young looking. I remember when I was a young kid in the early 2000s I remember every kid had a baseball hat which is why I threw my leather one on.
