J.Crew Outlet is carrying a skirt that is pretty close to the Taffeta Rugby Skirt (or at least I think so, since I've never seen the retail skirt myself). The skirt at J.Crew Outlet is item number 12702. It is numerically-sized, and was marked $98. It was not on sale when I tried it on.
The skirt has on-seam pockets, which I think are a cute touch. I don't carry much in my pockets, but they are high enough to give you a nice place to stick your hands if you don't know what else to do with them. The skirt is a little full, owing to a bit of pleating, but doesn't make you look wider or thicker than you are, which is always nice.
Again, no extra volume from the back. The pleating is frequent enough so that it is full without being boring and just hanging there.
I left this skirt at the outlet because of the price, but also because of the colors. While I think the orangey-red and grey colours work well together, and still make for a cute skirt, I just didn't love them enough in this skirt together to take it home. At the time, I couldn't recall which retail skirt this was mimicking, but I much prefer the orange and pink.
