1920's Black (Blue?) Crape Dress

From the seller:

This is so gorgeous! I bought this in a vintage clothing store in the mid-1980's and only wore it a couple times. It has been in storage in a climate-controlled, acid-free environment since about 1988. This is in pristine condition for its age. I believe it is silk. And I am pretty sure the belt buckle is celluloid, but it might be bakelite. Not sure. The quality of this is amazing - lots of hand stitching and just gorgeous. Classic 1920's dress - the real thing.

This is truly an incredible find! It has been very well preserved and cared for. It is approximately a size 6. I don't sew, and am hesitant to post measurements as I don't do those very well.

Please ask any questions before bidding. Remember that pictures are part of the description, and that with any vintage item, it is not brand new. Thank you.

Thanks for your questions. This is truly an incredible dress - it is so well made and there are a couple tiny tiny pinholes (about 3) when you hold it up to the light - pics added here. this is such a great example of a 1920's dress and in very good condition for its age. Measurements are:
Navy 20s drop waist
Some Pinholes
Shoulder-17 1/2
Bust- 42
Waist - 38
Hip- 38

From Me:

Although I'm sure it looks Navy Blue to our eyes today, I believe it was original black that simply faded over time. I've had items that I swore up and down were black until many washes and years later and they've become a very dark blue or very dark brown. It's pretty normal with the dark colors.

I'm also not sure if this one is silk - I really think this was a mourning dress. The Victorian rules for mourning were going away at this point but some of the upper classes still practiced them as well as being popular in more Catholic countries. A wool crape would make perfect sense for a mourning dress. There is already an excellent article up on mourning practices to include an excerpt from 1922's Vogue. The white trim would be acceptable a few weeks after the funeral.
