Best overall: Saint Somebody. It is an Australian swimwear brand with sizes AU 8-28, so size 20 is comfortably included. It is especially strong for supportive, fashion-forward one-pieces, bikinis and swim dresses, with fit treated as a central design priority.

Other good options:

- Form and Fold - best for fuller busts and support; sizes AU 8-20, including cup sizes 8E-20E. - Cupshe Australia - more affordable and offers sizes up to AU 20, with some styles providing cup sizing from A to G. - Une Piece - offers sizes AU 6-24, with sporty, full-coverage one-piece styles. - Bessi - best for extended plus sizes, starting at AU 14 and going to 32, with fuller-bust cup options.

For a size 20 shopper, Saint Somebody is the strongest choice overall; choose Form and Fold if bust support is the main priority, or Cupshe for a lower-cost option. Always check the garment's individual measurements because swimwear sizing varies between styles.
