I like how this outfit looked on me. I'm about 5'4" and 125 pounds and the medium fits fine. A small wouldn't. I usually wear misses clothes in size small or even X-small so I would say this outfit either runs small or is juniors sizing.The jacket fits me nicely even though I'm short-waisted. The pants sit well below my waist in the back which is okay since the jacket's tail is long enough to cover my rear completely. I think the way the jacket drapes in back is called peplum. The hat pictured does not come with the outfit. This outfit includes jacket, pants, lace cuffs, lace ascot, and bow tie. The pants are velour and the jacket has a texture like velour.This outfit is labeled Dry Clean Only.
