Custom lingerie vs standard sizing: what the difference actually is
By Cron Renown atelier,
Standard bra sizing works well for a specific range of body proportions. Outside that range, the fit compromises multiply: the band rides up, the straps slip, the cup gaps or overflows. Custom sizing addresses these problems by starting from the individual body rather than from a size chart. This article explains what the difference actually involves.
What standard sizing assumes
Standard sizing assumes a predictable relationship between band size and cup volume, and between cup volume and cup shape. These relationships hold for a portion of the population. For people whose proportions fall outside the assumed range, the standard size that fits the band will not fit the cup, or vice versa.
The range of standard sizes has expanded over the years, but the underlying assumption has not changed: that body proportions cluster in predictable ways. Custom sizing makes no such assumption.
What custom sizing actually measures
Custom sizing starts with the individual measurements rather than with a size category. At Cron Renown, the seven-measurement intake covers band circumference at two breath points, bust circumference, underbust circumference, breast projection, breast base width and strap length.
These seven numbers together describe a body shape that no size letter can capture. The pattern is then adjusted to match those numbers rather than to approximate them.
When custom sizing makes the most difference
Custom sizing makes the most difference for people whose proportions fall outside the standard range: a narrow back with a larger cup, a wide back with a smaller cup, asymmetrical cup volumes, a short torso that makes standard strap lengths too long.
It also makes a difference for people who have found a standard size that fits adequately but have never found one that fits well. The gap between adequate and well is where most of the comfort improvement happens.
The trade-off
Custom sizing takes longer and costs more than buying a standard size. The process involves a measurement stage, a swatch stage and a production time of three to four weeks. For people who have found standard sizing works for them, the trade-off may not be worth it.
For people who have not, it usually is.
