Yeah that’s weird about the measurements,
I'm still waiting for the results of the BSP CEO’s reply to explain whether they did Bjork

I appreciated all your help, Jimmy!

So yeah the shirt is like near deadstock and also for measurements is 15”x19-20” or 50x65 in centimeters
and also double/double.

When I tried to match the details my bjork on the website it also similar looks like

The typical BSP tag looks similar with my björk shirt and that’s same measurements so tricky

Yes, that’s tricky and someone say it's FAKE, but just want to know scientifically or legitimately here..
I've shown more photos of the measurements and stitching detail from the back seam tag stitches

Haven’t no idea to legitimate this shirt,
I’ve send as zoomed on the print, and that’s double stitched at all

Can anyone help me?…
