Quick Answer

The My Necessity FlexFit Nursing Bra uses a proprietary FlexFit technology that expands up to four cup sizes, letting you wear one bra from early pregnancy through postpartum without guessing your size.

Why FlexFit Matters for Your Changing Body

During pregnancy and breastfeeding, your breast size can shift by several cup sizes. A bra that fits perfectly one month may feel too tight or too loose the next. The My Necessity FlexFit Nursing Bra addresses this with a seamless, wirefree design that stretches to accommodate growth without losing support.

Unlike traditional nursing bras that rely on multiple hook-and-eye rows or band adjustments, FlexFit technology works through the fabric itself. The ultra-soft recycled nylon blend expands evenly, so you don't get pressure points or gaps. This makes it a practical choice for hospital, sleep, and everyday wear.

Common Sizing Mistake: Choosing by Pre-Pregnancy Size

Many shoppers pick a size based on their pre-pregnancy band and cup, then find the bra uncomfortable a few weeks later. The FlexFit design compensates for cup growth, but the band should still fit snugly from the start. If you're between band sizes, choose the larger band to allow for rib cage expansion during late pregnancy.

How to Get the Right FlexFit Fit

  1. Measure Your Underbust: Use a soft tape measure around your rib cage, directly under your bust. Keep the tape snug but not tight. Round to the nearest whole inch. This gives your band size. Common mistake: measuring over clothing or pulling the tape too loose, which leads to a band that shifts during wear.
  2. Choose Your Band Size from the Size Guide: Match your underbust measurement to the My Necessity size guide. For example, if your underbust is 30–32 inches, start with size S. If you're at the upper end or expecting significant rib cage expansion, consider the next band size up. Checkpoint: The band should feel snug on the loosest hook when new. If it's tight on the loosest hook, size up.
  3. Test the Cup Stretch: Put on the bra and scoop your breast tissue fully into the cup. The FlexFit fabric should stretch to cover your breast without gaping or digging. If the fabric pulls tight across the fullest part, you may need a larger band or a different style. Common mistake: assuming the cup must fit perfectly without stretch. FlexFit is designed to expand, so slight snugness is normal and will ease as your body changes.
  4. Adjust the Straps and Check Support: The straps should sit comfortably on your shoulders without slipping or digging. Raise your arms and move around. The bra should stay in place without riding up. If the band rides up in back, it's too large. Checkpoint: A well-fitting FlexFit bra provides light support without underwire. If you need more structure, consider a different nursing bra style.
