πŸ§β€β™€οΈ Prefer to Measure Manually?

No problem β€” you can easily find your size by following the guidelines below πŸ‘‡

  1. 1️⃣ Start with your body size (8–18)
    Use your hip and waist measurements to select your body size on the table.
    πŸ‘‰ These measurements are standard sizing and stay the same across all bust sizes.
  2. 2️⃣ Then choose your bust size (L–XXL)
    Match your full bust measurement to the closest fit on the table below:
        β€’ Bust L β†’ Extra 4cm of fabric around the bust only, over & above a standard fit (approx D/DD bra fit)
        β€’ Bust XL β†’ Extra 8.5cm of fabric around the bust only, over & above a standard fit (approx E/F bra cup)
        β€’ Bust XXL β†’ Extra 13cm of fabric around the bust only, over & above a standard fit (approx G/H/I bra cup)
    πŸ‘‰ This system allows you to find a dress that fits both your body and your bust β€” without compromising on shape.
  3. πŸ“ Tip: Always measure your bust at the fullest point, keeping the tape level, for the most accurate fit.
