We women go through so many physical changes in a lifetime that it’s no wonder our bra size can fluctuate. Sometimes the cup fits just right, but the band on your bra suddenly feels too snug. In this case, many women turn to bra extenders. Bra extenders are just rectangular pieces of fabric that typically hook onto the hook & eye closure of the bra back to extend the length of the band 1-3 inches. During pregnancy, certain times of the month or if you experience a sudden weight gain, you might think a bra extender is the solution. And yes, these extenders can be a good solution.
