True & Co
Data-driven bra fitting -- their quiz has helped millions find their size
The Algorithm That Knows Your Bra Size Better Than You Do
True & Co was founded in 2012 by Michelle Lam, a self-described algorithm geek who had spent her career evaluating investments at Bain Capital Ventures. Frustrated by the universally awful experience of bra shopping — the harsh fitting room lighting, the limited sizes, the reliance on "fit models" whose proportions matched almost no one — Lam applied a data scientist's mentality to an industry that had been guessing at fit for over a century. She built a sixteen-question quiz that mapped body shape, current bra frustrations, and fit preferences to generate personalized size recommendations, creating what would become one of the most comprehensive fit datasets in intimate apparel.
What Makes True & Co Different
True & Co's innovation was using data to expose how broken traditional bra sizing actually is. Over a million women took the Fit Finder quiz, generating more than 22 million data points that revealed something the industry didn't want to hear: the standard sizing model, based on perfectly proportioned fit models Lam called "mythical," failed the vast majority of real bodies. From this data, Lam's team created True Spectrum — a framework identifying over 6,000 different body types, giving women a more nuanced understanding of their shape beyond a number and a letter. The bras themselves were then engineered using this data, not traditional fit models, resulting in bras that fit real bodies rather than idealized ones.
Key Product Lines
The True Body Collection is the core offering — wire-free bras in scoop, V-neck, and racerback styles designed using the True Spectrum data. These bras use a seamless knit construction that stretches and contours to the body rather than forcing the body into a predetermined shape. True Body Lift adds light support for those who want gentle shaping without underwire. Lace options bring feminine detailing to the data-driven fit.
Who True & Co Is Best For
True & Co is for anyone who has tried dozens of bras and never found one that fits right. If you suspect your "correct" size isn't actually correct — if your band rides up, your straps dig in, or your cups gap despite wearing the size a department store told you to wear — True & Co's quiz and data-driven approach may finally solve the puzzle. It's particularly valuable for women between standard sizes or with body proportions that don't match conventional sizing charts.
Price and Sizing
Bras from $38 to $58, underwear from $14 to $22. Sizes from 32A through 42G. Following acquisition by PVH (Calvin Klein's parent company) in 2017 and later sale to Basic Resources in 2023, the brand remains focused on the fit-first philosophy that built it.
