How to measure

  • Snug but comfortable — not tight
  • Note to the nearest ½ inch or cm

Full Bust Measurement
Measure around the fullest part of your chest. Keep the tape horizontal and relaxed.
BUST

Tips for accuracy

  • Wear a non-padded bra or go bra-free
  • Measure across the fullest part
  • Use a mirror to keep tape level
  • Don't pull tight — tape should rest gently

Fit Tips for You
🎀
Band: Should sit firmly and horizontally. You should fit two fingers underneath — snug, never painful.
Cups: Breasts should fill the cups fully — no gaps, no spillage. Wrinkles = go down a cup; overflow = go up.
🌸
Straps: Should sit comfortably on your shoulders. 80% of support comes from the band — not the straps.
