Bra Size Calculator – Frequently Asked Questions
1. How do you measure your bra size correctly?
To measure your bra size correctly, you need two measurements: underbust and overbust. Use a soft measuring tape and measure around your ribcage directly under your bust for the band size, and around the fullest part of your bust for the cup size.
2. What is underbust measurement?
Underbust measurement is taken directly below your breasts around the ribcage. This measurement helps determine your band size which provides most of the support in a bra.
3. What is bust or overbust measurement?
Overbust measurement is taken around the fullest part of your breasts. This measurement helps determine the cup size of your bra.
4. How often should you measure your bra size?
It is recommended to measure your bra size every 6 to 12 months. Body changes, weight changes, pregnancy, or hormonal changes can affect your bra size.
5. What if my bra size falls between two sizes?
If your bra size falls between two sizes, it is usually better to choose the larger band size or the cup size that feels more comfortable and supportive.
6. Why is it important to wear the correct bra size?
Wearing the correct bra size improves comfort, posture, and breast support. A properly fitting bra also enhances the shape of clothing and prevents back and shoulder discomfort.
7. What are common signs of a wrong bra size?
Common signs include straps digging into shoulders, band riding up your back, cups overflowing, gaps in the cups, or discomfort while wearing the bra.
8. Can bra size change over time?
Yes, bra size can change due to weight fluctuations, pregnancy, hormonal changes, or aging. That is why regular measurement is recommended.
9. What type of bra is best for everyday use?
T-shirt bras and full coverage bras are usually best for everyday wear because they provide comfort, smooth shaping, and good support throughout the day.
10. Does the band or the straps provide more support?
The band provides about 80% of the support in a bra while straps provide around 20%. That is why a properly fitting band is very important.
