Understanding the Difference Between Bra Size & Cup Size

Finding the right bra starts with knowing the difference between bra size and cup size — two parts that work together to give you the perfect fit.

🧷 Bra Size (Band Size)

This is the number part of your bra size — like 32, 34, 36, 38 and so on.
It refers to the measurement around your ribcage, just under your bust. The band provides most of the support in a bra, so getting this right is essential.

Cup Size

This is the letter in your bra size — A, B, C, D, E, etc.
Cup size refers to the volume of your breasts, or how much space they take up in the bra. It works in relation to your band size, which means a 34C and a 36C will have different actual cup volumes.

💡 Why It Matters?

A well-fitting bra isn’t just about comfort — it improves posture, enhances your silhouette, and supports your everyday movement.
Wearing the wrong size can lead to back pain, shoulder strain, and even skin irritation.

Always try on new styles and sizes, especially if your body changes.
