One of my favorite purchases in recent memory is this J.Crew Elena shirtdress in striped cotton poplin. I *love* the chic covered buttons, the smocked tie waist, and the full skirt! It’s a classic silhouette that’s flattering for many ages and for many occasions — my mother-in-law bought the olive green version to wear into fall. This is the size 0 — if you’re deciding between two sizes, I would go with your smaller size!
