Bra Fitting Tips
- The band should provide 80% of the support, not the straps
- The center gore should lie flat against your sternum
- Your breasts should be fully contained within the cups
- The underwire should rest flat against your ribcage
- Re-measure every 6-12 months or after weight changes
Frequently Asked Questions
You should measure your bra size at least once a year, or whenever you notice changes in your body. Factors like weight loss or gain, pregnancy, menopause, or even changes in exercise routines can affect your bra size. It’s also a good idea to measure if you’re experiencing discomfort with your current bras.
Wearing the correct bra size is essential for both comfort and health. A well-fitting bra provides proper support, reduces back and shoulder pain, prevents tissue damage, and improves your posture. It also enhances your appearance by creating a smoother silhouette under clothing and boosting your confidence.
Common signs of an ill-fitting bra include: straps digging into your shoulders, band riding up your back, underwire poking or sitting on breast tissue, spillage over the top or sides of cups, gaps between the cups and your breasts, and red marks or indentations after removing the bra. If you experience any of these, it’s time to remeasure.
Yes, bra sizes can vary significantly between brands and even between different styles within the same brand. Our calculator provides a standard starting point, but you may need to try sister sizes (one band size up and one cup size down, or vice versa) to find your perfect fit in different brands.
A correctly fitting bra should have: a band that’s snug but not tight (you should be able to fit two fingers under it), cups that fully contain your breasts without gaps or spillage, a center gore that lies flat against your sternum, and straps that provide support without digging in. When you jump or move, your breasts should stay in place.
