This is such a classic silhouette! I love the hardware details on the bodice, and the cream lines are really flattering. I ordered this in an XL (my standard is XL for non-smocked bodices), and I was on the fence about sizing up because of the sleeves and shoulders with this one, but I stuck with the XL. I am a little bit restrained with my arm movements, but nothing crazy. If you're really wide through the shoulders or have bigger arms, I would size up.
