I'm 5ft 3.75in and 53kg and it fits slim and t-shirt dress-like but I recommend a pair of under thin material shorts or tights underneath as it is not intended as a dress.
Unfortunately it loses shape quickly even while putting my hands in the pockets to straighten them out. I wore it with a thin belt which helped with the loosening somewhat but still tends to get bigger while wearing it.
It does however stand up well in the wash and does not fade (although the graphic did crack a little). I ordered the garment in Gray and I can liken it to the color of a medium heather gray pocket tee. Expect a richer gray.
