Vintage 1970s tiered white / cream lace maxi gown

Here is a gorgeous long sleeve, mock neck boho dress by Betty Lane. Feels like a blend of fabrics, made in the USA. Soft tan with lace and beautiful stitching details throughout. Five decorative buttons on the front, with two clasps and a 22" zipper down the back. Fairly heavy weight, definitely not a breezy summer dress. Absolutely stunning, and in excellent condition with tons of life left. See photos of arm length, waist and waist to floor length.
