Women’s apparel is a 600B industry. It is highly segmented, and literal armies of people analyze category and product performance across millions of skus. So spending a lot of time on something like this is definitely not unusual.
I had some first and second-hand knowledge around pricing household appliances. There's a common assumption that "the manufacturer says 'charge X'", the retailer charges X+Y% and you all go home happy. And you could not be further from the truth if you tried: pricing is an insanely complicated process with negotiation from both sides and monitored by an army of secret shoppers to keep both sides honest.
