I followed the advice of other reviewers and ordered a size down; I usually wear a size 6 so I ordered a 4.  It does indeed seem to run big, because the 4 fits but a 6 would probably be falling down.  I love the color and material, I haven't had to put it to a stain test yet but it seems like the fabric would shrug off spills like it does wrinkles.  Water just beads on the surface.  It is a perfect length and cut and I've had some comments on how cute it is.  It isn't clingy like poly/cotton, and I like how it looks a little sporty but I can still wear it to work.  And pockets!  How I love to have somewhere to put my phone if nothing else.
