I found a bra that is circle stitched, but has plastic shoulder strap adjusters. There's no label, but I'm fairly certain this is cotton. What era is this bra? I'm quite confused.
Can you post more pics of the interior, seams, etc? This could be vintage... someone might've replaced those clips along the way.
I highly doubt this is repro, but I am just not sure of the era. I know the circle stitch was popular in the 50s, but the clips are plastic. That makes me think 60s, but in the sixties the stitches would be different. I'm just so confused!
It's just really hard to see the details needed to determine era... INTERIOR seam photos help as well as CLOSE up of the other details like elastic and clips. Even if the clips a modern replacement (which I think), how they are attached is important. Good luck with it!
I think you have a very early 60's bra, it is adorable. I used to collect vintage Bra's, and have seen many 1960's bras with plastic fittings.Often they look very 1950s in the cup shape.
