Vintage sheath dress with jeweled collar

This is a vintage silk blend fully lined sheath dress. I wear a modern size 8 and while I have a little room in this, it is not huge. Sizes have changed with the times! The color is a bit yellowing - not really sure if this is a factor of age or how it always was? There are some marks that I’ve taken pictures of - I have not tried to remove these as I am not a domestic goddess by any stretch and would probably ruin it! I have considered dyeing it black! Back zip, fully lined. Really cool dress! The estate sale I bought it at - the homeowners were antique dealers and traveled to Asia frequently for inventory shopping. I was told by the daughter that this and the other one listed were purchased during one of these trips. Non-smoking house
