60s Glittery Shift Dress

1960s shift dress. Zips up the back. It is 3 ft long from shoulder to bottom. I tried it on. I'm 5'6 and it hit me just above the knee, so it's longer than I expected, but the sleeves were about 3" short. It's also not as loose fitting as expected. I'm 2 sizes smaller. Keep in mind that clothes from the '60s may be sized somewhat smaller than they are now,bad Americans get larger overall. I'm thinking this is a bit closer to a current size 10. The waist is not tapered; it's what was called a "shift" dress back in the 60s.
