I don't think tucking a shirt into the front of a pair of bikini bottoms is a good look for anyone... even if Jenna Lyons says so.
However, if you're in need of a spring/summer look from J. Crew I just saw this dress at the factory store and it is incredibly well made and so cute. The texture doesn't photograph well, but it's very thick with horizontal bands around it. The ivory would be perfect for a rehearsal dinner or summer date night. Sadly, I don't need it.
Happy weekend!
