The number in a bra size refers to the band size, which is the measurement around your ribcage, just below your bust. This number corresponds to inches or centimeters and determines the circumference of your torso. The letter in a bra size represents the cup size, which is based on the difference between your bust measurement and your band size. Cup sizes are typically labeled with letters such as A, B, C, D, etc. With each letter representing a specific range of measurements.
It’s important to understand that the combination of both the number and letter in a bra size determines the overall fit of the bra. For example, if you wear a 36C bra, it means that your band measures 36 inches or centimeters around and there’s approximately a 3-inch difference between this measurement and your bust measurement.
A common misconception about bra sizing is that once you know your numerical band size and alphabetical cup size, you can wear any bra in that same size. However, due to variations in brand sizing and different styles (such as demi cups or plunge bras), it’s essential to try on various bras within your calculated range to ensure an optimal fit.
A less-known fact about bras is that different countries may have slightly different sizing systems. For instance, European brands often use centimeters for band sizes while UK brands typically use inches. Knowing this information can be useful when shopping for bras from international retailers or when traveling abroad.
