Mindset Shift: from “fixing flaws” to designing for actuality

By educating the FBA as a regular sample adjustment fairly than a “particular drawback,” we shift the narrative: our bodies usually are not incorrect; patterns are incomplete measurement—so the shoulders and higher chest match—after which add the bust quantity the sample by no means accounted for.
