I bought this awesome blazer on poshmark, and it says it's a medium, but it ran too small.I am so disappointed. I marked it small because it is tight.I would say it's a size 4 I.M a size six. Was very tight in the arms and snug once zipped. It's used obviously it's in great condition.It's fully lined.It has the zipper and then the zipper pockets that are real pockets. It is a blue with cream throughout.It's a beautiful jacket. Any questions? Please let me know
