One of my favorite things to do when I choose outfits is to match colors. I chose purple leggings with my Irma top from LuLaRoe because the outline of the stripes on the shirt is the exact same shade of purple.
Also, it's important if you want to really expand your wardrobe that you choose solid tops and solid bottoms. Solid bottoms always go well with printed tops and solid tops always go with printed bottoms.
Are you comfortable with being as color coordinated as I am?
