70's / 80's Vintage White Sundress w/ Embroidered Collar

This dress is around 40+ years old, from 1977-1983(ish). Super cute, but I haven't fit into it in a long while, and my closet real estate calls for me to pass it on. Purchased it from a seller that takes vintage clothes and touches up any flaws from aging, so it's in really good shape. There's a slip on the bottom half, but the top half is just sheer fabric. I like to wear a black or vibrant color full coverage bra with it It's a size L, but fits like a large size M or a small size L. Runs small. Has belt loop!
