These pants are very cute, comfortable and light weight. They are generously sized, so no need for sizing up. I did it and had to return and order my lower size. The medium is very generous, but not too large.
They are thin, the fabric is a bit more flimsy than I expected looking at the picture, that's why only four stars. Otherwise, no complaints.
I purchased them in gray and they look very nice. Be prepared to iron :)
