I used to wear a dress 2-3 times a week. I can't tell you how many people commented about how much effort I put into those days. I knew it was cheating, just pull a dress over your head, slip on sandals and you're done. Somewhere over the course of the last 5 years, I've stopped wearing them.
This combination from JCrew along with a few others I spotted in there this evening, have me rethinking the casual dress. It is certain to be back in my spring wardrobe.
