I don't own a lot of navy pieces, not because I'm opposed to the color, but find that if I'm going to go with a neutral, most of the time it will be either black or white. I picked up this romper a while back and love that it's not just daytime appropriate. The structured fabric and peek-a-boo back makes it the ideal piece for transitioning from flats by the beach to strappy sandals for evenings.
P.S. The romper has since sold out, but I also love the geometric detailed back on this one.
