Eber Vintage plaid acetate maxi dress

Such a cool unique vintage piece. Blue plaid acetate midi dress from Eber. Very lightweight material. Tags appear that this was never worn or washed. Junior vintage size 13 but just fits my siZe 6 mannequin so runs quite small. I believe this is a 1970's piece. Love the button collar. Also has matching button trim at sleeve cuffs. Attached belt ties in back. Front has hidden buttons all the way down. . Some signs of discoloration on the collar area due to age.
