Edit: Thanks to reader's comments, I went inspecting the interior finishing on this blouse, and have confirmed it is NOT antique, but from the 1970s/1980s instead! I admit I was fooled, but actually I feel a lot better about wearing it now. The style is certainly similar to 19teens blouses (as you'll see below), so I do intend to still wear it with 19teens ensembles.
Edit 2: After inspecting this blouse even further, I'm not convinced it is 1970s. The interior seams are overlocked with cotton or linen thread by what I'm confident is hand, but not ALL the seams are overlocked. My guess is that somebody stabilized or repaired this antique blouse at some point after its initial manufacture. Other parts of the blouse, such as the type of fabric and interfacing, bone buttons, cut, and finishing point to it being much older.
So my final verdict:
I just don't know.
|I haven't had the blouse cleaned or pressed yet. I've paired it here, just for photos, with a blue wool skirt - not period (probably 1950s, but could be much younger), but has lines similar to later 19teens skirts.|
|What you can't see in the picture is that the back is gathered to a twill ribbon tie, which comes around the front, to corral the blouse - very Edwardian|
