My girlfriend loves these pajamas. She says the fit is just right (petite large,) and at her height of 53, says they don't need to be hemmed. She also loves the blue color and design. (So do I.)  These are a high quality cotton/poly blend - the stitching is very good and the piping around the neck gives the top a nice stylistic flourish.

If there is such a thing as perfect PJs, these might just be them.
