Chunky white sweater, black leggings and black shoes (can be heels, but no need. Biker boots work just as well). Just make sure the sweater (or shirt beneath) covers your butt. That's simple leggings rules. This outfit is very easy, yet pretty.
I have this curtain in my babys nursery. I love seeing the light shine through the die-cut stars, just like the twinkle twinkle of the night sky. The curtain also casts the coolest shadows on the wall in the morning light.
