Frankly, I'm only showing you the top of this dress because that's all you need to know. The skirt could be finished with blaze-orange pom-pom trim, and you should still want this dress. (I exaggerate only slightly.) Click on the image to go to this dress's listing on http://www.fashiondig.com, which is archaeological in the best possible way. In that "omg we found King Tut's tomb!1!!!1" way. Without any pesky curses (so far). Anyway, check it out. (The site had six pages of 1950s dresses alone!)
This particular one is B38/W30 and $75. It's hard to find a good black vintage dress in top condition — obviously, because if it's flattering at all, whoever owned it first probably wore the hell out of it. I have one that I treasure, made of a fabric so stiff it can stand on its own in Chicago winds, with velvet-trimmed pockets. I imagine that the first owner died unexpectedly immediately after purchasing it (perhaps even on the way home from the shop), and that her distraught husband kept everything exactly as she had left it for, oh, fifty-five years. Which is patently untrue, and actually kind of creepy, but that's what I like to think.
I'm sure nothing like that is involved in the backstory of this dress. I'm sure it was a freak landslide in the middle of the night that buried Miss Tammy's Frock Nook, preserving all the clothes inside perfectly until the construction of a new highway bypass brought them to the attention of FashionDig. Absolutely.
