🧍‍♀️ Prefer to Measure Manually?

No problem — you can easily find your size by following the guidelines below 👇

  1. 1️⃣ Start with your body size (8–22)
    Use your waist and hip measurements to select your body size on the table.
    👉 These measurements are standard sizing and stay the same across all bust sizes.
  2. 2️⃣ Then choose your bust size (M–XXL)
    Match your full bust measurement to the closest fit on the table below:
        • Bust M → Bust has 4cm extra around the bust over & above a standard fit (approx D/DD bra fit)
        • Bust L → Hourglass shape — bust and hips are roughly equal (approx E bra cup)
        • Bust XL → Bust is about 2 cm larger than hips (approx F/G bra cup)
        • Bust XXL → Bust is about 5 cm larger than hips (approx H/I bra cup)
    👉 This system allows you to find a dress that fits both your body and your bust — without compromising on shape.
  3. 3️⃣ Bust larger than XXL?
    If your bust is larger than the XXL size for your body (8–22), simply email us — we may be able to make a custom fit for you ✨

📏 Tip: Always measure your bust at the fullest point, keeping the tape level, for the most accurate fit.

Heidi's Collection has a relaxed waist fitting

A little extra “ease” is built into each garment to give you room to move comfortably — so you can sit, stretch, and breathe without straining the seams.

👉 If your measurements don’t match the chart exactly, just choose the closest fit — the ease will take care of the rest.
