How to Measure
-
Chest (Bust): Around the fullest part of your bust (tape level).
-
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.
