Best Underwired Bikini Top
Freya Samba Underwired Bikini Top — 8.5/10 (D–K). An underwired bikini top provides the same support mechanism as a regular bra — because it essentially is one. The Freya Samba is the most consistently well-reviewed D+ bikini top, with genuine support and a flattering shape. Pair with any bikini bottom of your choice for a mix-and-match approach that solves the separate-sizing problem entirely.
Best Full Swimsuit
Fantasie Versailles Underwired Swimsuit — 8.3/10 (D–K). Underwired one-piece with internal cup support; one of the most reliable swimsuit constructions available in D+ sizing. The built-in underwire means no compromising on support for a one-piece aesthetic.
Best Tankini
Panache Anya Tankini Top — 8.1/10 (D–J). The Panache Anya uses the same support engineering as their regular bras in a tankini format; more coverage than a bikini with better support than most swimsuits. Good for women who prefer more torso coverage.
Sizing Note
D+ swimwear is sized using standard UK bra sizing for the top — order using your correct bra size rather than a generic swimwear size. Mix-and-match bikini sizing (top and bottom separately) is the most practical approach for curvy and busty figures.
