I bought this in my usual size small, and it fits great.  While it doesn't quite have the anti-static properties of my favorite Farr West half-slips, it keeps my dresses from clinging to my tights, especially during these dry winter months.  The reversible nature is great, and the higher side works great under wrap or lower-cut dresses.  The straps are also adjustable (which is great for us shorter gals), and it has enough fabric so that it doesn't stretch and get sheer across the bustline if you have a D-sized chest.  Great slip for the price!
