Understanding Your Victoria's Secret Bra Size
Finding the perfect bra size is crucial for comfort, support, and the overall look of your clothing. While many women wear the wrong size, a few simple measurements can provide a great starting point, especially when shopping at stores like Victoria's Secret.
Why Bra Sizing Matters
A well-fitting bra can prevent discomfort like shoulder pain, backaches, and digging straps. It also enhances your silhouette, making your clothes fit better and boosting your confidence. Victoria's Secret, known for its wide range of styles, emphasizes a good fit to ensure their bras look and feel their best.
How to Measure for Your Bra Size
To use our calculator effectively, you'll need two key measurements, taken in inches. It's best to measure while wearing a non-padded bra or no bra at all, and stand upright with a relaxed posture.
Underbust Measurement (Band Size):
Wrap a soft measuring tape snugly around your rib cage, directly underneath your bust. Make sure the tape is level all the way around your back. Breathe out to get the smallest possible measurement. This measurement helps determine your band size.
Example: If your snug underbust measurement is 30.5 inches.
Bust Measurement (Cup Size):
Wrap the measuring tape loosely around the fullest part of your bust. Ensure the tape is level and not too tight, allowing for natural breast tissue. This measurement, combined with your band size, helps determine your cup size.
Example: If your bust measurement at the fullest part is 36 inches.
How the Victoria's Secret Bra Size Calculator Works
Our calculator uses a standard method often employed by Victoria's Secret and other major bra retailers:
Band Size Calculation: Your snug underbust measurement is rounded to the nearest whole number. If this number is odd, we add one inch to arrive at an even band size (e.g., 31 inches rounds to 31, then becomes a 32 band). Victoria's Secret typically offers band sizes starting from 30 or 32.
Using our example: 30.5 inches (underbust) rounds to 31. Since 31 is odd, we add 1, resulting in a 32 band size.
Cup Size Calculation: The difference between your bust measurement and your calculated band size determines your cup letter. Each inch of difference corresponds to a specific cup size:
Less than 0.5 inch difference = AA
1 inch difference = A cup
2 inch difference = B cup
3 inch difference = C cup
4 inch difference = D cup
5 inch difference = DD (E) cup
6 inch difference = DDD (F) cup
7 inch difference = G cup
8 inch difference = H cup
Using our example: 36 inches (bust) – 32 inches (band) = 4 inches difference. A 4-inch difference corresponds to a D cup.
Putting It Together: An Example
If your underbust measurement is 30.5 inches and your bust measurement is 36 inches:
Band Size: 30.5 rounds to 31, then becomes 32.
Cup Size: 36 (bust) – 32 (band) = 4 inches difference, which is a D cup.
Estimated Bra Size: 32D
Important Considerations
While this calculator provides a strong estimate, it's important to remember that bra sizing isn't an exact science. Factors like breast shape, brand variations, and personal preference can influence the perfect fit. We highly recommend using this calculated size as a starting point and trying on bras to ensure the best comfort and support. A professional bra fitting at a Victoria's Secret store can also provide personalized recommendations.
