Understanding Bra Sizes

Bra sizing can be complex, with many women unknowingly wearing the wrong size. The traditional system uses a combination of a number (band size) and a letter (cup size) to identify the bra size. For example, in a 38D size, the “38” refers to the band size, while the “D” indicates the cup size.

Band Size

The band size represents the measurement around your rib cage, just beneath your breasts. To measure your band size, wrap a measuring tape around your torso, ensuring it’s snug but not too tight. Round the measurement to the nearest whole number. If this number is even, add four inches; if odd, add five inches. This method is commonly recommended by sources like www.thirdlove.com and www.sizechart.com.

Cup Size

Cup size is determined by measuring around the fullest part of your bust. The difference between the band size and bust measurement will help you find your cup size. For example, if your bust measures 40 inches and your band size is 38, the difference is 2 inches, which corresponds to a “D” cup.

Sister Sizes

Understanding sister sizes can help you find a better fit if your usual size is not available. Sister sizes are sizes that have the same cup volume but different band sizes. For instance, 38D has sister sizes of 36DD and 40C. This concept is crucial, as it allows for flexibility in fit and comfort.

Why 38D is Considered Average

According to data from brametric.com, approximately 1.34% of women in the United States wear a 38D bra size. This size represents a significant demographic of women, making it one of the more commonly sought sizes. The average breast weight for a 38D size is about 3.4 lbs (1.53 kg), with a volume of around 52 cubic inches (848 cm³).

Common Misconceptions about Bra Sizes

Many women believe that a larger band size automatically indicates a larger cup size, but this is not true. For example, a 36DD and a 38D do not hold the same breast volume, as the band size difference affects the fit. This misconception often leads to discomfort and poor support. Sources like www.restonyc.com emphasize the importance of understanding these distinctions to choose the right size.

Finding the Right Fit

Measuring at Home

To ensure the best fit, you can measure yourself at home. Use a soft measuring tape and follow these steps:

1. Measure your band size: Wrap the tape around your rib cage just underneath your bust and take note of the measurement.
2. Measure your bust size: Measure around the fullest part of your bust while wearing a non-padded bra.
3. Calculate the cup size: Subtract your band size from your bust size to determine your cup size.

Trying on Bras

When trying on bras, pay attention to the following:

• Adjust the straps: Ensure that the straps are snug but not digging into your shoulders.
• Check the band: The band should sit level around your torso and not ride up.
• Cup Coverage: There should be no spillage or gaps in the cups.
