This costume is so cute and it goes perfectly with the male version.  We received so many compliments on our costume.  I also ordered the size Medium, which is my normal size, but I had to order the next size up.  The Large fit in the skirt part, but the top fit a little big on me, but not enough to be a problem.  The length in the size Large was also a bit longer which I prefer over the Medium.  Ladies, if you're a bit larger on the bottom, please order a size up if you want a little more coverage.  Overall, it's the perfect couples Halloween costume.
