Size 18J 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.

J cup at Brava

J cup is genuinely rare territory in global retail. The brands that design for J cup — Elomi, Panache, Goddess, Ewa Michalak, Sculptresse — do so with specific construction decisions around wire length, cup height, and band engineering that reflect what the size actually requires. Brava has the widest J cup selection in Australia, which is a meaningful range for a size that most retailers treat as exceptional. Women wearing J cup who were previously fitted into HH are not uncommon at Brava — at this cup size, the visual difference between a well-fitted bra and an undersized one is significant.

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.
