How to Measure

  1. Chest (Bust): Around the fullest part of your bust (tape level).

  2. Underbust: Directly under your breasts around the ribcage.

For the bikini top, focus on bust coverage and cup height.

Important Fit Notes

  • Cup Height = Coverage

    • This is a string‐tie triangle top. Each 1–2 cm in cup height roughly adds one cup‐size worth of coverage. If you have a fuller bust (C/D+), consider going up a size for more coverage.

  • String Ties Are Adjustable

    • You can tighten the chest/neck ties to fit a smaller ribcage. That’s why you may need to size up for bust coverage, even if you typically wear a smaller band size in bras.
