Beautiful 50’s style dress w/ red polkadots size 3X… runs small

This dress is almost vintage it was purchased over 15 years ago in Beverly Hills California. I never wore the dress but I love the dress, never had an opportunity to wear it. And now I have lost 70 pounds so there’s not gonna be any time soon that I will be able to wear it so my loss your gain. It’s a stunning dress in tan with red polkadots Banabee is the brand. I think it’s a little smaller than a 3X may be a 1X or 2X. Armpit to armpit 21 inches length from the shoulder down 42 1/2 inches
