Here it is, owing from some time ago about the potential sizing problem. Sorry it took so long to locate the faulty measuring tape and finally take a picture of it. I kept is far away from my sewing area.... for obvious reasons ;)
The blue tape is the normal one, showing the correct measurements.
The white tape is the faulty one. I have a waist measurement reading 21" with it! No, my waist is definitely not 21".
