Delicate floral satin material dress

Beautiful floral dress from Princess Polly. Never worn. I love this dress it looks very delicate and elegant. Tag says US 4 but could fit a 0/2 or size up slightly because is a loose material. Slightly too big on me but I lost the tag so was not able to return it so was never worn and in new condition. The material is not know but feels and looks like satin
