Is a I cup the same in every brand?
Not quite. The letter on the label depends on the brand’s sizing system and how deep its cups run — and a few brands skip cup letters entirely. Here’s how the brands that make a I cup run. Your band changes which cup you need too, so for an exact match translate your full size.
| Brand | Sizing | How its cups run |
|---|---|---|
| Elomi | UK sizing | UK plus-size full-bust; cups run generous. |
| Fantasie | UK sizing | UK sizing; consistent fit. |
| Freya | UK sizing | UK sizing; bands run snug. |
| Glamorise | US sizing | US full-figure; true to size. |
| Panache | UK sizing | UK sizing; true to size, consistent year over year. |
| ThirdLove | US sizing | Half-cup sizing available; cups run slightly generous. |
| Wacoal | US sizing | True to size; consistent fit across decades. |
