trying to date women's workwear - 1940s but with serged seams?

[Snake Charmer Vintage]

Hello VFG forums - this is my first ever post on this forum. Hello!

I thrifted a women's vintage boiler suit (woven cotton, grey-blue in colour) and I'm dying to figure out its age. It has clearly had the front zipper replaced, but otherwise it looks 1940s in terms of construction and tailoring. The thing that's throwing me is the serged seams - I know workwear was manufactured with sergers before the 1950s, but I don't have a lot of experience with workwear from this era. Any insights appreciated! I'm trying to upload a pic but keep getting an error message. Will try again later.

Welcome! Looking forward to seeing pictures. Error messages can be caused by photos that are too "heavy" for the system to handle - it has happened to me more than once. Maybe try re-sizing?

OK! Will do.

These look 40s. Or they could be 70s. It's hard to tell exactly from the photos provided. The overlock serger was patented in the late 1800s. They have been used commercially for some time.

My impression from the photos provided is 1960s-ish.
Can we see a good clear photo of any tags? There appears to be one at the neckline.

That is a nice find. I agree it looks more 1960s or 1970s than 1940s. I might expect a 1940s work garment to be made of thicker and sturdier material.

Made me think of Rosie the Riveter in Norman Rockwell's original 1943 image! I know she is wearing dungarees rather than all
in one overalls but it just struck me as having a similar look.

Rosie is indeed wearing all in one overalls.
