The Hotmilk My Necessity 2.0 FlexFit is a seamless, wirefree nursing bra designed for the stretch and unpredictability of pregnancy through postpartum. Made from recycled nylon, it expands up to four cup sizes so it keeps fitting as your body changes — without needing to size up mid-trimester or in the middle of the night.
Features
- Flexible sizing expands up to 4 cup sizes — keeps fitting through the size fluctuations of pregnancy and postpartum
- One-handed drop-down nursing clips — easy access when you're holding a baby and running on four hours of sleep
- Side-sling nursing access — supports skin-to-skin contact without fully removing the bra
- Removable contour cups — wear with or without for smooth shaping or a more relaxed feel
- Half-adjustable straps with 6-hook back closure — more fit options than a standard pull-on style
- Seamless, wirefree construction — comfortable enough to wear overnight without digging or pinching
- Made from recycled nylon — soft against sensitive postpartum skin

SISTER SIZING
Sister sizing allows you to find your perfect fit. Sometimes after measuring yourself it is possible that your size may still need to be adjusted.
The following chart shows sister sizing for each bra size. All of the sister cups in the same row are the same size.
Sister sizing is like a seesaw. If you move up in the band, move down in the cup and vice versa. For example if you find that a size 34E fits well in the cup, but is too big around the band, go down to the next sister size in the row and try a 32F.
