Presumably if you’re not wealthy enough to afford all 3, then a full cup will resolve 90% of your needs, and you can fallback to cheaper bras for the uncommon case (which is a significant improvement over what is the apparent norm; 100% of the time your bra is uncomfortable reduced to 10%, for $350)

And ofc if you’re often wearing non-“everyday” outfits.. you’re probably spending quite a bit on clothing anyways, and can probably afford 2-3 at the $350 price range
