How can you tell a girl's breast size?

You can tell a girl's breast size using measurements and a bra sizing chart.

Measuring for Bra Size

Determining breast size involves taking two key measurements, as detailed in the YouTube video How to Measure Your Bra Size ft. Jenna Curran:

Band Size:
- Measure around your chest, directly under your breasts.
- Keep the tape measure snug, but not too tight.
- Take a deep breath and exhale to ensure accuracy.
- This measurement is the foundation for the band size.
Bust Size:
- Measure around the fullest part of your chest, usually over the nipples.
- Keep the tape measure parallel to the ground and snug.

After obtaining the band and bust measurements, you can calculate the cup size.

Calculate the Difference: Subtract the band size from the bust size.
- Example: If your bust measures 36 inches and your band measures 34 inches, the difference is 2 inches.
Determine Cup Size: The difference between bust and band size corresponds to a specific cup size. Generally:

Difference (inches) Cup Size

1 A

2 B

3 C

4 D

5 DD or E

6 DDD or F

7 G

The above table is a generalization. Sizing can vary slightly between brands.
Combined Measurement: The final bra size consists of the band size and the calculated cup size.

Professional Fitting: For the most accurate bra size, consider getting a professional bra fitting at a lingerie store.
Brand Differences: Bra sizes can vary between different brands and styles, so it's important to try on bras before buying.
Comfort: Ultimately, a comfortable fit is most important. Choose a size that feels supportive without being too tight or too loose.
Visual Estimation: Visually estimating breast size is not accurate. Precise measurements provide a reliable way to determine size.
