Dress sizes are based on bust, waist and hip measurements, but brands cut differently and vanity sizing has shifted sizes over time. When your measurements fall in different sizes, choose the larger one and have the dress taken in where needed, or use the size that fits the part of the garment that matters most (bust for fitted tops, hips for fitted skirts).

What each result means
- US size = min([Size index], 12)
- UK size = min([Size index], 12)
- EU size (DE/FR −2) = min([Size index], 12)
- Letter size = min([Size index], 12)
Formula
Each measurement is matched to a standard size chart; the recommended size is the largest of the three so the dress fits everywhere
