Vintage floral granny dress

Vintage floral granny dress, size 7/8, made in SRI Lanka, in South Asia, thinking this is an 80's dress. The tags yellowed, but dress is in very good condition, no rips or stains, buttons down the front, sleeves are like a silky material, button on the wrist area, ties around to the back, multi color, I washed the dress in delicate, because it had been packed away and had the musty smell, after the first set of pics. The tag on the dress faded so you can't see now where it was made and the size faded too, but the first pic I took of the tag has all the information on it
