Vintage 60s vivid neon pinks and blues maxi halter dress by Glenbrooke
Amazing piece, exactly what you hope for in a dress form this era! :)

The good news is there's no holes or big dark stains, really it's in great condition for being half a century old 

There are a few minor flaws, I found a stain just under the bodice in the petal of a flower, it's pretty faint be visible
The hem need re stitching (I pinned it with 2 tiny safety pins for now which works fine)
A stain is on the inside of that hem
and a small seam rip in the slit on the back of the skirt (pretty typical for skirts like this and very minor)

All basic normal vintage condition, I just like to be as thorough as possible

No size or fabric tag, feels like the classic medium weigh polyester or acrylic blend used back then
NO STRETCH!
bust measures 15 inches pit to pit, cups looks to be a smallish B cup
empire waist seam (under the cups) measures 14 inches across
true waist is 16 inches across
top of shoulder to the top of that empire waist seam is 11 inches
hips are 20 inches across
length is 52 inches
