This is the third product I have purchased. While I absolutely love the fabric, I have found inconsistency in the sizing.  The first one I bought was a perfect fit.  The second one, of the same type (different style than this one) was just a little smaller than the first.  This one fits larger than the first two.  As they are just for sleep, not a huge deal, and all are working fine for that purpose- and again, I love the fabric and the over all quality.
