This is my first ever vintage eBay purchase. (I got it at a pretty darn good price too, which apparently is tricky on eBay.)
The dress is late 1940's -- no zipper -- and features rhinestone buttons down the front, and darling pockets with an embroidered flora motif and rhinestone studs. It has the classic 40's A-line silhouette and and is made of pink cotton material in which the weave is visible. It also came with a thin purple belt with brass clasps (shown above). Bonus!
