So, i usually find that retailer tops run large (everywhere else i'm a medium, but i'm always a small at retailer) but with pants or slacks i'm usually an 8 and i always have to size up in retailer to a 10, but based on some of the other "runs large" reviews, i stuck with my normal size 8 and they fit perfectly! super cute. not lined, but the material has a nice weight to it, so that doesn't bother me. will def be wearing to the office.
