I think this Ella Moss top would look great under just about any color suit or paired with solid pencil skirt. And I bet the top is especially good for the work - to - evening transition. I love the combination of deeper blues and light blues hinted with sea foam green all set against a mellow grey, the ruffles at the collar, and the feminine, yet not overdone tie.
The top is made from cotton -- vegan, of course! It is $98; available here through Anthropologie.
