RARE Vintage 1960s Mod orange gray dress with original price tag! Fits 14

Vintage 1960s dress (coat dress style). Still has original price tag of $40 (that would be approx $458 today). Super comfortable warm and very moveable fabric. Made of 50% wool ??acrylic and ??acetate. Size on tag says 16 but I wear a 14 and fits me great!! 3/4 length sleeves. Knee length. I have not had it dry-cleaned because I did not want to ruin the original tag
