At E cup a one-piece has to do two jobs at once: hold the bust securely and stay comfortable while wet, when fabric relaxes and any weakness in the construction shows up immediately.
What to look for at E cup
Underwired or firmly moulded cups, side support panels, and a band that fastens rather than simply stretching over the head. A suit that pulls on with no fastening rarely holds an E cup bust in place through a swim.
Styles and brands
Fantasie Swim and Panache Swim are the most consistent at E cup, with Freya Swim adding brighter prints. If you would rather buy top and bottom separately, see E cup bikini tops and the full all E cup swimwear range.
