Bra Sizing Simplified
Bra sizing is based on two measurements: the band size and the cup size.
Band size: To determine your band size, measure around your rib cage, directly under your bust. Round your measurement to the nearest whole number.
Cup size: To determine your cup size, measure around the fullest part of your bust. Subtract your band size from this number, and use the difference to find your cup size on the chart below.
| Difference | Cup Size |
|---|---|
| 0 | AA |
| 1 | A |
| 2 | B |
| 3 | C |
| 4 | D |
| 5 | DD/E |
| 6 | DDD/F |
| 7 | G |
| 8 | H |
| 9 | I |
| 10 | J |
Choosing the Right Bra for Every Activity
Beyond getting the size right, it's worth matching the style to how the bra will actually be used. A sports bra with a wider band and secure straps works best for running, jumping, or other high-impact activity. A wireless bralette with adjustable straps and hook-and-eye closures suits everyday wear and developing bodies. A halter or backless bra shifts support to a neck strap for special-occasion necklines, while an everyday bra with a back closure offers the most adjustability as sizes change.
