Common Questions about My Necessity Bra
Everything you need to know about seamless FlexFit sizing, Regular vs Busty fit, and hospital bag use
The Necessity is sized S–XXL, so start with your usual clothing size for the band. For the cup, choose from two options: Regular (A–DD) or Busty (E–G). Select your current cup size — the fabric stretches 2–3 cup sizes to accommodate your changing shape as your milk comes in. If you're between sizes, we recommend sizing up.
Yes — it's one of our top hospital bag recommendations. Here's why:
- Seamless construction — no pressure points from day one
