Wrap the measuring tape around your ribcage directly beneath your bust. The tape should be snug, level, and parallel to the floor. Note the measurement in inches. If the number is even, add 4 inches to determine your band size. If the number is odd, add 5 inches. For example, if your ribcage measures 30 inches, your band size is 34. If it measures 31 inches, your band size is 36. ### How to Measure Your Bust Measure around the fullest part of your chest, typically across the nipples. Keep the tape loose enough that it does not compress your breast tissue, and ensure it remains level across your back. Note this measurement in inches.
### Calculating Your Cup Size Subtract your calculated band size from your bust measurement. The difference in inches determines your cup size: * A difference of 1 inch corresponds to an A cup. * A difference of 2 inches corresponds to a B cup. * A difference of 3 inches corresponds to a C cup. * A difference of 4 inches corresponds to a D cup. * A difference of 5 inches corresponds to a DD (or E) cup. * A difference of 6 inches corresponds to a DDD (or F) cup. For example, if your bust measurement is 38 inches and your calculated band size is 34, the 4-inch difference indicates a starting size of 34D.
## Matching Vanity Fair Styles to Your Breast Shape Your numerical size is only a starting point. Breast shape determines how the tissue fills the cups, which influences which Vanity Fair styles will fit you best. ### Round and Full Shapes If your breasts have equal fullness at the top and bottom, you have a round shape. Full-coverage bras are ideal for this shape because they contain all the tissue without creating a line where the cup meets the skin. Vanity Fair’s full-figure styles, such as the Beauty Back series, offer taller cups and supportive bands that prevent spilling.
### Shallow or Bottom-Heavy Shapes If your breast tissue is concentrated at the bottom or you have a shallow profile with less volume at the top, full-coverage cups may gap or pucker at the top. Look for demi-cup, plunge, or contoured t-shirt bras. These styles lift the tissue from below to fill out the cup naturally. ### East-West or Side-Set Shapes If your breasts point outward toward your arms or there is a wide space between them, look for bras with strong side support. Vanity Fair styles featuring side-smoothing bands and molded cups help gently push breast tissue toward the center, creating a more centered, forward-facing profile.
### Asymmetrical Shapes It is common to have one breast that is larger than the other. When choosing a bra, always fit the cups to the larger breast to prevent spilling. You can then adjust the shoulder strap on the smaller side to secure the cup, or choose a style with stretch-lace cups that conform to both sides. ## How to Verify a Proper Fit After putting on a Vanity Fair bra, perform a quick check to ensure the size and style are correct:
* **The Band:** The band provides the majority of the support. It should sit level around your body, parallel to the floor. If the band rides up your back, it is too large, and you should try a smaller band size. * **The Cups:** Your breasts should fit smoothly inside the cups. Spilling over the top or sides indicates the cup size is too small. Gapping or wrinkling in the fabric indicates the cup size is too large. * **The Center Gore:** The flat fabric panel between the cups should lie flat against your breastbone. If it lifts or sits on top of your breast tissue, the cups are too small. * **The Straps:** Straps should stay in place without slipping off your shoulders or digging into your skin. If they dig in, the band may be too loose, forcing the straps to carry too much weight. ## Using Sister Sizes to Adjust Your Fit If a bra fits well in the cups but the band feels too tight or too loose, you can adjust your fit using sister sizes. Sister sizes share the same cup volume but have different band sizes. * **To go up a band size:** Go up one band size and down one cup size (e.g., move from a 34D to a 36C). * **To go down a band size:** Go down one band size and up one cup size (e.g., move from a 36C to a 34D).
Using these adjustments helps you fine-tune your fit to match your unique body shape.
