Amazing vintage 1970s white and cream lace gown

This is an incredible dress from the 1970s, perfect for a summer party, wedding, or wedding rehearsal look. White with cream lace at the hem and sleeves. Wide boatneck. Fully lined. The back closure is fabric covered buttons. Over the buttons is a bow with long tails cascading down the back. No fabric tag but it feels like a cotton or linen canvas. No flaws.
