Unfortunately, there's no single "common" girls bra size due to varying body shapes and growth stages. Bra size is determined by both band size (the measurement around the ribcage) and cup size (the difference between the band size and the measurement around the fullest part of the bust).
Instead of a single answer, understanding how bra sizes relate to standard clothing sizes is more helpful. As the provided reference suggests:
- Small: Often corresponds to a 32C or 32D.
- Medium: Often corresponds to a 34C or 34D.
- Large: Often corresponds to a 36C or 36D.
Important Considerations:
- Individual Variation: These are general correlations, and individual body shapes vary significantly. Accurate measurement is always best.
- Bra Styles: Different bra styles can fit differently.
- Growth Spurts: Girls often experience growth spurts, requiring frequent re-measuring.
- Proper Fit: A well-fitting bra should be comfortable, provide adequate support, and not dig into the skin or create bulges.
How to Determine Bra Size:
- Measure the Band Size: Measure directly under the bust where the band will sit. Round to the nearest whole number. This is the band size.
- Measure the Bust Size: Measure around the fullest part of the bust, keeping the measuring tape level.
- Calculate Cup Size: Subtract the band size from the bust size. The difference determines the cup size:
- 1 inch = A cup
- 2 inches = B cup
- 3 inches = C cup
- 4 inches = D cup
- And so on...
It's always recommended to visit a lingerie store or department store for a professional bra fitting to ensure the best possible fit.
