My Necessity Wirefree Nursing Bra: Busty Fit Guide

Quick answer

For a secure fit with the My Necessity Wirefree Nursing Bra, start with your pre-pregnancy band size and use the flexible cup sizing to accommodate up to four cup changes.

How to fit the My Necessity Wirefree Nursing Bra for a busty shape

1. Measure your band size while braless: Wrap a measuring tape snugly under your bust, right where the bra band sits. Round to the nearest even number. This is your starting band size. For the My Necessity bra, choose that band size — do not size up in the band for extra room. A too-loose band is the most common cause of poor support in wirefree bras.
2. Select your cup size based on your largest pregnancy measurement: Measure around the fullest part of your bust while wearing a non-padded bra. Subtract your band measurement from this number. Each inch equals one cup size. Because the bra expands up to four cup sizes, choose a cup that matches your current or anticipated largest size, not your pre-pregnancy size. If you are between cup sizes, go up — the flexible fabric will accommodate the extra room.
3. Check the band fit with the two-finger test: Put on the bra and fasten it on the loosest hook. Slide two fingers under the band at your back. If the band lifts or you can fit more than two fingers, the band is too loose. If you cannot fit two fingers, go up one band size. The band should stay parallel to the floor and not ride up when you raise your arms.
4. Adjust the straps for gentle tension, not lift: Wirefree bras rely on the band for support, not the straps. Tighten the straps just enough so they stay in place without digging into your shoulders. If the straps slip off, the band may be too large or the straps are over-tightened. Red marks from straps that fade quickly are normal; deep grooves that stay mean the straps are too tight.
5. Test the fit by moving and feeding: Wear the bra for 15 minutes at home. Bend, stretch, and raise your arms. If the bra shifts or the cups gap, recheck the band size. For nursing access, pull the cup down — the fabric should release the nipple easily without the whole bra moving. If the cup fabric bunches or wrinkles, the cup size may be too large despite the flexible sizing.
