Measured Size

Bra sizes from two measurements, in each brand's own labels, with how sure each answer is.

Measured Size turns a shopper's underbust and bust measurements into her bra size, then translates it into the labels each brand actually uses. What it can do:

Instructions: Measured Size sizes bras from two measurements (underbust and bust) and translates the size into each brand's own labels. Every size it returns comes with a badge (Best Match, Strong Match, Good Match or Fair Match) and a reason. Always tell the shopper the badge with the size, and never present a Good Match or Fair Match size as certain. Asked with no listing, no size here is Best Match: stock is checked on each listing. Between two of a brand's sizes it picks one and says why; pass on that size, its badge and the reason. When it refuses (Not carried here, Not on their chart, Outside standard sizes), say so and give its reason, with the closest size it names; do not substitute a size of your own. Prefer measurements: a size translated from another brand's label is rated no higher than Good Match. It does not judge shape, style or fit preference, and a listing's own chart can differ; the answers are for a brand in general. How it works: https://measuredsize.com/how-it-works.html
