The band should feel secure without digging in; cups and straps should feel comfortable as you move.

How the BRABAR guide works
Uses the manufacturer’s published band ranges. The cup label comes from comparing the bust with the calculated band, not a generic rule borrowed from another brand.

Bands are garment labels, not body ranges. Some combinations may be missing from this chart, and chart coverage is not a stock check.
Source scope and chart notes
Uses the official EZ-Fit instructions: rib cage to nearest even band (published example 33 → 34), fullest bust to nearest whole inch (37.8 → 38), then bust minus that band (38 − 34 = 4, D). Checked numeric-band subset 28–38, A–DDD; the separate Small/Medium/Large table is not substituted. The guide does not establish availability of every numeric label.
Let’s find your starting point
Measure over a t-shirt or a lightly lined bra, or without one—whichever feels right.
A number can guide you. Your comfort gets the final say.
Bra sizing isn’t consistent from one label—or even one style—to the next. Think of this as a useful first try, not a rule you have to fit.
If your first try is close but not quite right, compare neighboring sizes and another style or cut.
Brands use different patterns, fabrics, and size ranges. A mismatch says more about the garment than about you.
