I originally ordered a size up based on some of the reviews but ended up having to return the Medium for a Small instead. The Medium was much too wide and loose on me. I'm 5'2" and 116 lbs, and the Small fits me perfectly -- flowy, without being too loose or too snug. The material is like an average quality bedsheet, it's not the softest, but I'm hoping it will soften up with washes over time. The white is sheer, but the pin tucked detail over the chest makes that part opaque, which is perfect. There's lace embroidery on the arms which I didn't notice in the pictures. It makes it a little more Victorian than I'd like, but I still love this and think it will be perfect for the warmer weather nights that are on the way. And my grandma would be happy that I'm keeping my shoulders covered, as she always warned that bare shoulders would give me arthritis when I'm older. ;] The nightgown that I originally wanted was the "Eileen West Women's Floral Embroidered Cotton Lawn Ruffle Ballet Nightgown", but the price point was too high for me to justify for sleepwear. Happy to have found this pretty and more affordable option.
