Size 18FF bras and swimwear

Size 18 is firmly in specialist plus-size territory. The number of brands maintaining full cup coverage at size 18 narrows, but Brava's selection at this band size focuses on those that do it properly. Elomi, Goddess, and Ulla are the strongest options across most cup sizes at size 18.

FF cup at Brava

FF cup sits between F and G in the specialist sizing scale and is used by most brands in the Brava range. The double-letter naming follows the convention used when the single-letter alphabet runs out at the larger end of the cup scale — FF is one increment above F, not a dramatically different size. That said, the difference between F and FF is meaningful in fit: women who find F cups that almost contain them but show a slight spillage at the top or sides are often correctly fitted in FF.

At size 18, the strongest brands in the range are those that specifically engineer for larger torso proportions — Elomi, Goddess, and Ulla among them. Browse the full plus size bras collection.
