We want you to have the perfect fit, and we know— better than most— that people come in all different sizes. Although very few will be exactly one size, the guide below should suffice in most cases. The most important measurement is the bust, as most gowns are forgiving through the waist and hips. For tips on measuring, see our FAQ. If you require custom sizing, choose "custom" on the size when you purchase and enter your measurements when prompted, or contact us for more information.
