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

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 explicit UK/US conversion rows, 30–44 A–H; A is absent at bands 40–44. The 42GG row prints a conflicting EU96 band and is withheld, not repaired; 42H remains usable. Native UK E corresponds to the source’s US DDD/F, not US E. Combined-cup, clothing and swim tables are not used. Label conversion of the general US band/cup starting estimate only, not a manufacturer body-measurement calculation or a fit guarantee. Confirm the chart on the specific style.
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.
