I generally wear a plus size 2X in blouses like this and so I ordered an XXL in beige... the fit was perfect.  Maybe a tad snug on the waist.  But it was a generally comfortable fit and felt like my size.  I have other Devon and Jones shirts in another style and I really appreciate that the my size didn't change just because I picked a different style.  No surprises in size.

 I would have kept it if the beige wasn't so see-through.  I ended up returning it... but I may get a darker color in this style a little later.  At this time I was only needing beige.  It's a nice shirt and the quality was otherwise great.
