I'm in love with this combo. The striped sweater is white with black stripes. The polkadot shirt is navy with white dots. And the leggings are black. I love mixing those neutrals together. And the taupe shoes just set it off. :)
Oh and just a little side note, the polkadot shirt is actually backwards. The front had a V neck like the sweater so to really see the polkadot top I turned it around. Try it with your favorite dresses and tops. It makes you think that you have more clothes in your closet than you actually do.
