Everything about this gown is perfect.
Fit is relaxed and comfortable while being flattering and modest
Fabric is incredibly soft, and thick enough not to be see through
The gown washes and dries like a dream.  Looks perfect and wrinkle free right out of the dryer.
This is a quality garment that should last for years.
Sizing:  I am 5'5" and weigh 160.  I got a large and could have probably got by with a medium.
