⚡ CalcWolf Insight

An estimated 80% of women wear an incorrect bra size. The most common error: wearing a band that is too loose and a cup that is too small. A properly fitted bra should get most of its support from the band (80%), not the straps (20%). If your straps are doing the heavy lifting and digging into your shoulders, your band is too big.
