At GG cup the difference between a swimsuit that works and one that does not is encapsulation: each side of the bust supported in its own structured cup, rather than pressed flat across the front. Compression alone gives no shape and no security.
What to look for at GG cup
Deep underwired cups, firm side panels to stop the bust migrating outward, and wide adjustable straps that can carry real weight without cutting in. Halter options help if you want extra lift, provided the neck tie is wide enough to spread the load.
Brands
Elomi Swim and Panache Swim are the mainstays at GG, with Fantasie Swim adding further options. See also all GG cup swimwear and one-piece swimsuit.
