Summer doesn't last very long in New York (although this summer it feels otherwise) so I usually try not to buy too many summer clothes. I often wear the same things over and over and over while mixing in pieces (like this shirt) that can transition into fall. When the pieces you choose have more personality (aka not jean shorts and a white tee) the combinations feel less monotonous and more exciting.
And of course you can't go wrong when you mix a big pattern + a small pattern in the same color family. Life lessons people. You heard it here first.
