Wacoal vs Chantelle
Two brands, two ways of grading a size. Here is how Wacoal and Chantelle differ in system, range and fit, and which one to choose for your shape and your problem.
Wacoal or Chantelle, in short
Wacoal and Chantelle use different systems (US vs FR / ES). Wacoal runs true to size in the band and true in the cup with average wires; Chantelle runs true to size in the band, true in the cup, wide wires. Range: Wacoal 30–46 / A–H; Chantelle FR 80–115 (US 30–44) / A–H. Convert your measured size into each and let fit decide.
Your measured size in both
Same body, two labels. Each result is your US size converted into the brand's system, then adjusted for how that brand grades. They use different systems, so the numbers differ even before fit.
