A business can easily charge more when a person super-sizes their meal. Yet it’s not so easy for companies that charge more due to a person’s size. And a company can charge higher fees for users needing more bandwidth when hosting multiple Web sites. But it becomes very tricky when a company scales its prices according to personal width.
One certainly pays more for an SUV than a hatchback because the SUV isn’t only richer in features, it’s more robust due to its sheer mass. And we don’t mind paying more for products that are of a genuine (or perceived) higher quality than those of lower stature– just look at the price of any branded product on your local supermarket shelf compared to the generic one it’s stacked next to.
In air travel, people now have to pay a premium when toting more of their stuff on the plane, or they get a discount for not using as much cargo space with their luggage. And while that has outraged some, it’s nothing compared to the heat airlines are facing in attempting to charge a higher price of plus-sized passengers that need more than one seat during their flights–even though that airline only has so many seats to sell during any given flight, and cannot otherwise recoup those costs and losses.
And that brings us to the recent debacle on boobs. Or, more specifically, the pricing of some bras supporting them.
British retailer Marks & Spencer, known for its reasonably priced lingerie, began charging more–as much as $3 USD more–for bras sized DD and up. And women balked, even took their plight to Facebook with their “Busts 4 Justice” campaign. The women behind the site argued that other retailers did not charge more for bigger sizes so Marks & Spencer shouldn’t either. Further fueling their argument, they noted that the store didn’t charge more for larger clothing sizes so the same should hold true for their undergarments.
In relenting to the female fury, the retailer just announced it will now price all its bras the same, and is wisely running a VERY clever campaign admitting “We Boobed.”, as well offering a further 25% off all bras for the month of May.
It’s true that when I buy a medium-size blouse I do not pay more than a woman buying a small-sized one– or less than a woman buying one in a large size. Same thing with shoes, no matter the foot size, the shoes cost the same, even though boots in a size 8 absolutely necessitate more high-priced leather than ones in, say, a size 5.
Take my Editor here at MarketingProfs, Ann Handley. While I look up to Ann for her professionalism and prowess–at just 5′4″ with a petite frame–I literally look down at her due to my standing at 5′8″ (add a couple inches when in heels) with an average-size frame. And while I’d love nothing more than for she and I to take a day off from all this marketing gab and go on a shopping spree, I’d likely feel odd, perhaps even feel badly, if we both loved the same style dress, but when at the register I was required to pay more for mine in a medium to hers in a petite. Even though I’m otherwise content with my size and height.
And that bad feeling of mine? More likely than not, it would be transferred to the brand itself.
So, what’s my point? That with some products where simple logic (and basic economics) dictates that a dress, blouse or bra in a larger size necessitates more material–and thus costs more to produce–simply doesn’t apply with our markets. Nope, in these instances, facts give way to feelings. Even though the fact is that many people would save money if certain products were priced by size, in companies not doing so, feelings are spared across the board.
And feelings win over facts much of the time in marketing. We usually label it perception and we work for our markets to buy into the perceptions that we craft and the emotions we work hard to tie to our brands. Yet in these instances, the perception is not a strategy that marketers can create, it’s something our markets decide and we must heed accordingly.
It’s one thing when the product is “separate” from our person, like a super-sized meal, SUV or branded product. Yet it’s quite another thing entirely when the product is either worn on our person (like bras) or is priced differently due to our personal size (like airplane seats). And those brands that ruffle our sensitivities with size-based pricing? They can end up paying dearly– just ask Marks & Spencer who are taking a cut in profits this month due to the bra boycott (though in the long-term, the shopping incentive from the discount matched with the publicity yielded from the campaign will probably more than make up for the retailer’s short-term losses by winning back customers and attracting new ones).
In the future, it’s altogether likely that personal size-based pricing models will evolve and could even become commonplace. But in the interim, brands using these pricing tactics are going to be met with some mighty–one could even say busty!–backlash. All told, we best pay close attention to our market’s sensitivities or we may just find that our brands have boobed, too.

The amazing thing is that the material cost of most goods are not the major driver of pricing. My guess is that the different bra sizes are only fractionally different in cost of materials.
Isn’t the core problem that M&S is a value retailer and attempting to differentiate generic label goods based on sizing? It is easier to differentiate the pricing on different size clothes if you appeal to the consumer through branding. There are specific stores that cater to petite or full-figured ladies, similar to men’s Big&Tall stores. These brands likely get the premium that cannot be gained when you have one brand serving all sizes; side by side in a department store.
M&S failed to realize “just because you can doesn’t mean that you should”.
Thanks for the post.
2 points I would add:
1. The difference in materials cost for different sizes has always been averaged into pricing. Small people have always been subsidizing big people. The problem is that now we have too many big people and not enough small people subsidizing them. In the end prices will just be higher for everyone.
2. Have you ever shopped the men’s Big & Tall section at a major department store/clothing store? The prices are higher than the regular-sized guys’ clothing. Always has been. This whole thing is ridiculous to me.
And funny that you just used the word boob! I never thought that that would be the word to explain this but not what I think of it it might just be.
Thanks for the comments, folks.
. Where they did well is with their current campaign (just by note of how much press it’s received as I found out about it through CNN, a major news network vs. finding out through a trade magazine).
@Robert: Yes, Big & Tall Men’s Shops do charge more. And here’s another example: so do women’s shops that tailor to petite women! So, both large and small charge a premium for clothing that’s tailored/crafted especially for specific body types. And markets have no problem with this.
Where problems arise is when a shop catering to mass markets–meaning sizes across the board–charges more for a certain size, or in this case, sizes above a certain size. Here’s where feelings get hurt and ire gets sparked– at least that’s what I’m gleaning giving the Marks & Spencer’s example since women felt it was “unjust” (even dubbed their group Busts 4 “Justice”).
And I agree with you that prices will likely be increased across the board and everyone will end up paying more.
@NWGuy: I asked my friend who works in design about how much more fabric is needed for different sizes (as I truly have no clue). She said that between a small and a medium, or even small and large, it’s usually nominal. But that the difference in a small and XL is notable and that’s where the expense comes in. And to your good point (like Big & Tall, or Petite Boutiques), you can charge more through targeted branding– but not in an “all things to all sizes for cheap prices” environ like M&S. That’s where they boobed
They got a lot of free press about this gaff. I’m not so sure it WAS a mistake. This might be chalked up to a brilliant marketing move.
@Robert:
Would imagine that the difference in pricing for Big&Tall (or petites for that matter) has less to do with the (presumably trivial) cost of extra material and more to do with smaller production scale. Petite items, for example, may require less material, but it’s also the case that they’re not just shrunken versions of regular sizes. They have to be reproportioned for shorter frames, and that means all the setup costs are duplicated but spread over smaller number of customers. Mass market items are cheaper to produce than the sizes on the upper or lower end, especially when they’re marketed separately, since, as CK notes, you then have separate marketing and merchandising costs to consider, too.
Because of this, I don’t think it’s necessarily the case that our presumed and much-publicized collective fattening is going to automatically mean we all pay more. The mass market range is just moving upward; what used to be an outlying group that had to be served separately, at higher cost, is gradually becoming the norm, which can be efficiently served at scale.
