Inspiration - Kate Middleton
When in doubt? Shirt dress.
I love love love these new $25 sandals I picked up at Target. (They remind me a lot of these $188 J.Crew ones.) Comfy, cute and I feel like they update a lot of my existing summer clothes by being a 'current' sandal style with the single front strap.
(Inspiration photo was found online after I took this outfit picture so it sorta an eh match.)
