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
- FlexFit sizing removes the guesswork of your exact postpartum size
- Side-sling clip is intuitive even in the first days
Soft enough to wear overnight from the first night in hospital
Yes — My Necessity is our most-recommended sleep style:
- Seamless, no pressure points overnight
- Wirefree throughout
- 6-hook closure can be fastened loosely for overnight comfort
- Available in Regular (A–DD) and Busty (E–G)

- Busty — E–G cup, extra internal support panel for a fuller bust
Both use the same seamless FlexFit recycled nylon — choose based on your cup range. Still unsure? Chat with our fit team
My Necessity is pretty forgiving so we get far less returns on this style due to how adaptable it is. Choose your regular size.
