My Necessity FlexFit Busty: Adjusting Fit as Supply Changes

Quick answer

Start by resetting the band and straps rather than sizing down immediately. If the band still rides up or the cups gap after those adjustments, move to a smaller size or a more structured style.

Why FlexFit feels different as supply settles

The My Necessity FlexFit Busty is designed to expand up to four cup sizes, so it follows changes in fullness rather than holding one fixed shape. That flexibility is useful in the early weeks, but it also means the bra can feel looser once engorgement eases or feeding patterns become more predictable.

This is a fit change, not a defect. The same bra that felt snug at day five may need a different band setting or strap tension by week six.

When the issue is the band, not the cup

A band that climbs up your back or shifts when you lift your arms is usually too loose, even if the cups still feel full. Because the FlexFit fabric stretches, fastening on the tightest hook too early can leave you with no room to adjust later.

Check the band first: it should sit level and stay put when you move. If it does, the cup fit is the next thing to assess.

When to stop adjusting and change style

If you have reset the band, tightened the straps, and the bra still gaps at the top or offers less support than you need for daytime wear, further adjustment will not fix it. At that point, a smaller size or a more structured nursing bra is the better choice.

Keep the FlexFit for sleep, hospital stays, or low-support days rather than forcing it into a role it was not designed for.

Diagnose your fit issue

• Band rides up or shifts: Fasten on a tighter hook and shorten the straps slightly. If the band still moves, the bra is too loose overall. Recheck after a full feed when breasts are emptiest.
• Cups gap at the top: Tighten the straps one notch and smooth the cup edge. If gapping remains, the cup volume is too large for your current shape. Do not over-tighten straps to compensate; that pulls the band up.
• Support feels insufficient: Confirm the band is snug and level. If support is still lacking for daytime wear, switch to a more structured bra for those hours. Use the FlexFit for rest and recovery, not high-impact days.
• Everything feels loose after supply settles: Try a smaller size in the same style. If that is unavailable, choose a bra with more structured band and cup construction. Stop adjusting once the band and cups both fit correctly on the loosest hook.

Product facts

• My Necessity FlexFit Nursing Bra - Black Busty: Flexible sizing expands up to four cup sizes. This accommodates supply fluctuations, but it also means the fit changes as fullness settles, so periodic readjustment is expected.
