This is a dress from the J.Crew Outlet, which I've called the Pleated Eyelet Trim Dress (item #12549). This dress is alpha-sized, and was available in a few different colors, including this pink, a vibrant green, and a white. It retails for $59.50. (I feel compelled to note that I bought this dress a little while ago, and during my last trip to the outlets, I don't recall seeing it, but I also didn't spend too much time looking around.)
I really liked this dress, so I ended up picking up this dress in the pink color and also in green. As with the outlets (and any clothing store, I suppose), it's always a gamble - do I pick it up now when they have my size/color combination, or do I try to wait it out for a bit to see if it goes on sale, and risk not being able to get it? I didn't want to risk not being able to get these dresses later, so I took them home.
