I have not seen that video, but that woman's information is very misleading, in my opinion. Embroidered labels go back to the 19th century (1800s). Printed labels are still used. I have printed labels from the early 1900s and even late 1800s. There are much better ways to determine age than if the label is embroidered or not. Who is this woman? She does not sound reliable to me.
Also, her use of the term "old" is way too vague to be useful.
