The main difference between a D cup and a DD cup in bra size is the amount of breast tissue each size can accommodate. A D cup typically fits a bust measurement that is 4 inches larger than the ribcage measurement, while a DD cup accommodates a bust measurement that is 5 inches larger than the ribcage measurement. This means that the DD cup has more room for breast tissue compared to the D cup.
It’s important to keep in mind that these measurements are not standardized across all brands and styles of bras, so it’s crucial to always get professionally fitted to ensure you are wearing the correct size. Different types of bras (such as full coverage or balconette) will fit differently even within the same letter size, so trying on various styles may be necessary.
One common misconception about bra sizing is that going up one letter (e.g. from D to DD) simply means adding an inch to your bust measurement. In reality, each letter represents a specific increase in bust-to-ribcage ratio, meaning there is actually quite a significant difference between adjacent sizes.
A less-known fact about bra sizing is that certain brands may use different systems for determining sizes, which can lead to confusion when shopping for bras across various labels. Understanding this variation can help make finding the perfect fit less frustrating and ensure you end up with comfortable and supportive bras.
Now that you understand the differences between D and DD cups, I recommend getting measured by a professional fitter at our store before making any purchases. This will ensure you get accurate measurements and recommendations tailored specifically for your body shape and personal preferences.
I hope this information helps demystify bra sizing for you. Remember: finding the right fit can be transformative–both physically and mentally!
