I am not a large person, so ordering a Plus Sized Large was an odd concept for me.  However, looking at the sizing chart, it seemed this would be my size, and the dress looked cute so I gave it a try.

What you can't see in the picture is that the back is actually a stretch/ribbed material, and that there is an additional tie closure.  This is a good thing, because if this hadn't been there it would have been far too big for me.  However, it fits well in the shoulders and bust, so cinching the tie a little tighter works out well and causes a little more flair in the skirt.
