Find your perfect wedding dress size and flattering silhouette with our expert calculator — designed to simplify sizing across top designers like Kennedy Blue and Evelie.

Why the Wedding Dress Size & Body Shape Calculator Matters?

Selecting the perfect wedding dress is one of the most important decisions a bride will make. While design, fabric, and silhouette play a significant role in defining your bridal aesthetic, fit is paramount. A well-fitted gown enhances your natural shape, ensures comfort throughout the day, and contributes to a polished, confident appearance in photographs.

However, determining the correct size can be challenging. Unlike ready-to-wear clothing, bridal sizing is not standardized across designers. Variations in cut, structure, and brand-specific grading mean that a size 12 in one label may fit differently than a size 12 in another. Additionally, many brides are surprised to learn that bridal sizes typically run smaller than streetwear sizes, often requiring a jump of one to three sizes.

How Our Wedding Dress Size & Body Shape Calculator Works

Our calculator goes beyond a basic size chart by incorporating multi-dimensional data to deliver personalized recommendations. It is designed to account for:

• Individual body proportions (bust, waist, hips)
• Designer-specific fit variations (e.g., Kennedy Blue, Mori Lee, Justin Alexander)
• Body shape classification (hourglass, pear, apple, rectangle, inverted triangle)
• Hollow-to-hem ratio for length accuracy
• Size transition logic when measurements fall between standard sizes

The tool compares your inputs against a curated database of real bridal size charts, including those from leading designers such as Kennedy Blue and Evelie’s stocked labels. When your bust, waist, or hips fall into different sizes, the calculator applies the industry-standard rule: size up to the largest measurement. This ensures the garment can be altered down, which is far more feasible than letting it out.

How to Measure for a Wedding Dress: Best Practices

Accurate self-measurement is the foundation of successful bridal shopping, especially when purchasing online. To ensure precision, follow these professional guidelines:

Bust

Using a soft, flexible measuring tape, measure around the fullest part of your bust, passing under the arms and around the back. The tape should be level and parallel to the floor.
Important: Measure while wearing the type of supportive undergarment you plan to wear on your wedding day, as this can significantly affect the outcome.

Natural Waist

Stand upright and bend slightly to the side. The natural crease that forms is your natural waist — typically located just above the navel. Measure around the narrowest point of your torso. Avoid pulling in your stomach or holding your breath, as this can distort the measurement.

Hips

With your feet together, measure around the fullest part of your hips and buttocks — usually 7 to 9 inches below the natural waist. This measurement is critical for gowns with structured skirts, such as ballgowns or fit-and-flare silhouettes.

Hollow to Hem (Optional but Recommended)

Measure from the hollow of your throat (the dip at the base of the neck) straight down to the floor, wearing the heel height you intend to wear on your wedding day. This measurement ensures proper gown length and is particularly useful when ordering made-to-measure or off-the-rack gowns.

Body Shape and Silhouette Recommendations

Beyond size, proportion and silhouette are critical to achieving a flattering fit. The calculator analyzes your measurements to classify your body shape and suggest styles that enhance your natural form.
