Nothing in that article you've linked to says anything about what you've asserted.

Also, Victoria's Secret doesn't do 3/$100 bra sales.

I think it's more that I'm less likely to need to return a Victoria's Secret bra. Like most garments, once the tags are off they can't be returned. The problem is a bra can "fit" in the dressing room when I try it on for five minutes but I don't really know how comfortable it is until the tags are off and it's been worn for the day. Either way I can't return it but I'm far less likely to end up with an uncomfortable bra from Victoria's Secret than I am from Target. Although it definitely does sting a bit more when I end up with a $100 Vicky's bra that turns out to be super uncomfortable. That's the gamble though I suppose.

That’s an average. How many women have far fewer than that?

A lot of women, especially those who are hard to fit, get by with just 1-3 everyday bras that they wear to death because it’s just so frustrating (or impossible) to find more bras that only hurt a little instead of being absolute torture devices.

They may have additional bras for special purposes (such as strapless) or that they can’t really wear to work (lounge bras and bralettes and sports bras and flimsy sexy things that you wear for a few minutes on the way to the bedroom).

But they wear those few primary bras every single day until they wear out.

If you spend all day every day being poked in sensitive tissue by the end of a metal stick, being able to add just one or two perfectly fitting and painless bras to your closet could be game changing.

Other women have no difficulty finding bras that are painless - but their breasts are shaped so differently from manufacturers’ assumptions that finding one that’s both painless and flattering at the same time is basically impossible.

Again, even replacing one quad-boob-creating bra with one that’s flattering but can be worn comfortably all day is a win, even if you’re not going to replace your whole collection.

Do you look at a new bespoke shirt or jacket offering and expect nobody to buy any because replacing their entire wardrobe would be prohibitive?

They're cheap and fit a huge variety of sizes, if poorly. If you have larger breasts, you just wear two. Not the most comfortable, and doesn't look as nice under clothes as a bra that fits, but cost-effective.
