Mystery skirts

I found a couple of very interesting skirts at the City Wide Garage Sale recently. I thought I knew what their general time period was, but now I'm not so sure.

I know this blog doesn't have much of an audience, but if any of my three followers knows someone who knows about historical clothing and can show them the following pictures to help me date these skirts, I WILL LOVE YOU FOREVER.

SKIRT 1

Skirt 1

I found Skirt 1 in a pile of "small, mixed linens" at a vendor who sells linens by the pound. It's actually a skirt panel. I'm certain that it's a skirt because there's a little notch in the center front and creases from pleats that had been picked out at some point.

All pleats repinned.

The selvedge edges are preserved and it measures 29" wide.

I can't find a whole lot of info on historical fabric widths. I know that fabric came in a standard 36" width for a very long time, at least from the 1920s-1960s. I found a vendor of antique fabric online and most of her turn of the century fabrics are 29" wide.

I thought this style of skirt was Edwardian, with the lace insets. But I don't think this lace is considered insertion lace.

And the Edwardian summer dresses with the beautiful insertion lace are usually made of lawn, and this fabric is a sturdy twill-like fabric.

I'd like to restore this skirt panel as a fully functional skirt to be part of a historical costume, but I just can't seem to find anything quite like it, so I'm not sure what time frame to put it in.

SKIRT 2 

Skirt 2 is a silk chiffon number with a stunning panel of lace down one side. What kind of lace is this? Is it Venice lace? I know nothing except that I love it. 

There are traces of black net that once backed the lace. I didn't see any traces of this black net anywhere else on the skirt (i.e. at the waistband). 

The lace sash is mounted on a silk panel with the center cut out, and then attached to the waistband. It's not tacked down on the skirt. There is a silk panel behind the lace sash that is sewn as part of the skirt. 

The chiffon skirt is gathered and mounted on a silk waistband that fastens with hooks and eyes at the side. 

Actually, now that I'm thinking about it, I'm wondering--what side were skirts usually fastened in the "old days"? Could the skirt actually close in the back, with the lace sash hanging down the center front instead of the side? 

As you can see, the silk hem along the border is completely shattered. It's as brittle as old paper and crumbles if you even look at it. The same can be said for the silk panel behind the lace sash. Interestingly, the silk fabric of the waistband and the sash and the chiffon of the skirt are in excellent condition. 

I'd love to be able to recreate this skirt using that beautiful lace sash and make a whole outfit from it. 

When I saw this skirt I immediately thought "flapper skirt!!" but... This would be part of an evening ensemble, wouldn't it? I don't think separates were worn very much in the 20s, at least not in evening wear. Could this be from the teens?  Am I anywhere close to the ballpark in guessing its age?
