I worked in a garment factory (here in the U.S.) and much of the article is spot on, however the comment "All lingerie is handmade" is a bit disingenuous. AFAIK, ALL garments are hand made, all operations are broken down to small operations, and not one garment is EVER made by one person unless it's custom or designer made.
The factory I worked in started with spooled yarn an then:
The material was woven by machine, hand cut to a pattern, "thermo set" (in an oven to preshrink) and sent to many specialized seamstresses who only performed one operation and were paid by the piece according to the difficulty of the operation.
From memory from highest paid to lowest they were: zippers, collars (with labels), sleeve cuffs, garment seams, button holes and button fastening.
The process is unbelievably efficient, with the correct number of seamstresses at each operation to not cause bottlenecks in flow.
That said, the markup on Asian made stuff is astronomical. My ex and I were in Korea (last century) and brand name bras, sneakers, clothes etc. were being sold in "night markets" for five to under ten dollars. These were made kinda like a Robin Hood operation... "steal manufacturing facility that someone else paid for" The U.S company paid to setup an assembly line or paid a "tooling charge" and the orders were filled in the number of shifts needed to fill the order. If the assembly line produced a sufficient quantity in one shift, the manufacturer could easily run a second shift (or third) to make knock offs of the EXACT product with many of the same employees, and this is where a lot of the counterfeit or re-branded identical stuff comes from.
Question? If the education and "degree" that is required is so lauded, why in the world do I fit perfectly in some bras marked 34C, 36A, 36B, and 38A? (my best fit is 38A and sister size 36B) not to mention the variability of band size variations, this is ridiculous. Imagine getting tires for your car with such loose standards that you'd have to try them all on the rim to see if they fit? OK, I "get" sister sizes, and that boobs can have very different "shapes" but volume is still volume and cup sizes that can vary so much is not a sign that the degree the designer holds is worth very much.
