In great condition, no size labels that I can see. I notice popper buttons on the inner shoulders that would usually mean a cami was attached. I don't think that is the case with this dress as it is fully lined. So not sure of the purpose of them.
Size measures approximately as a Medium to Large.
Pit to pit laid flat measures approximately 20.5"
Shoulder to hem laid flat measures approximately 40.5"
Any questions please ask.
