A 90cm bust measurement can be converted into a bra size by considering both the band size and cup size. The band size is typically measured under the bust, while the cup size is determined by the difference between the bust and band measurements. In many European sizing systems, a 90cm bust might correspond to a 34B in UK sizes or a 75B in European sizes, assuming a band measurement of around 75cm.
How to Determine Bra Size from a 90cm Bust?
Understanding bra sizes involves two key measurements: the band size and the cup size. Here’s how you can determine your bra size if your bust measures 90cm:
-
Measure Your Band Size:
- Use a tape measure around your ribcage, just under your bust.
- Ensure the tape is snug and level. Note this measurement in centimeters.
-
Calculate the Cup Size:
- Subtract the band size from the bust measurement (90cm).
- Use the difference to determine the cup size. For instance, a 15cm difference typically corresponds to a B cup.
-
Combine for Your Bra Size:
- If your band size is 75cm, combining it with a B cup results in a 75B in European sizes.
Understanding Bra Sizing Systems
What Are the Differences Between Bra Sizing Systems?
Bra sizing can vary significantly across different regions. Here’s a quick guide to understanding these variations:
| Region | Band Size | Cup Size | Example Size |
|---|---|---|---|
| UK | Inches | A, B, C | 34B |
| Europe | Centimeters | A, B, C | 75B |
| US/Canada | Inches | A, B, C | 34B |
- UK/US Sizes: Use inches for band sizes. A band size of 34 inches with a B cup results in a 34B.
- European Sizes: Use centimeters for band sizes. A 75cm band with a B cup is a 75B.
How to Measure for the Perfect Fit?
Achieving the right fit involves more than just measuring. Here are some tips:
- Wear a Non-Padded Bra: Ensure accurate measurements by wearing a non-padded bra.
- Check the Fit: The band should be snug but not tight. It should sit level around your body.
- Adjust the Straps: Straps should be comfortable and not dig into your shoulders.
Common Bra Sizing Questions
What if My Measurements Are Between Sizes?
If your measurements fall between standard sizes, consider trying both the smaller and larger sizes to see which offers more comfort and support. Some brands offer half sizes or sister sizes, which can also be a good option.
How Often Should I Measure My Bra Size?
It’s recommended to measure your bra size every six months, or whenever you experience significant weight changes. This ensures you maintain comfort and support.
What Are Sister Sizes in Bras?
Sister sizes are alternative bra sizes that offer the same cup volume but different band sizes. For example, if you wear a 34B, your sister sizes could be 32C or 36A.
- Example:
- 34B: Same cup volume as 32C and 36A.
Can Bra Size Change Over Time?
Yes, factors such as weight fluctuations, hormonal changes, and aging can affect your bra size. Regular measurements help ensure continued comfort and support.
How Can I Ensure a Comfortable Bra Fit?
- Try Different Styles: Different bra styles offer varying fits. Experiment to find what suits your body shape.
- Adjust Regularly: Ensure your bra straps and band are adjusted for optimal comfort.
