Types of nursing bra
Seam-free stretch bras
Soft, knitted, pull-on or hook-back bras, usually in S to XL. Very forgiving of size changes and comfortable around the clock. Best for the early weeks, for sleep, and for smaller to medium busts. Support is limited at fuller cup sizes.
Soft-cup, non-wired nursing bras
Sold in band and cup sizes, with seamed fabric cups. More support and a better shape than a stretch bra, while staying flexible. A good everyday choice at any size.
Moulded or T-shirt nursing bras
A smooth foam cup that hides breast pads and gives a neat line under clothes. Fixed cups cope less well with fluctuation, so they suit established feeding better than the first weeks.
Flexi-wire and wired nursing bras
These give more lift and separation, which many people with fuller busts prefer. Fit is critical. Buy once your size has settled and check that the wire sits on ribcage all round.
Nursing sports bras and pumping bras
Sports bras with drop cups for exercise, and bras with openings that hold pump flanges for hands-free expressing.
By stage
- Late pregnancy and the first six weeks: seam-free stretch or soft-cup non-wired, with room in the cup.
- Established feeding: soft-cup or moulded for everyday, with flexi-wire if you want it.
- Night: a sleep bra. See sleep bras for pregnancy and nursing.
By cup size
- A to D: most types work. Stretch bras are often enough.
- DD to F: choose band-and-cup sizing with a full sling and wide straps.
- FF and above: look to full-bust brands, several of which make nursing bras in the same UK sizes as their main ranges, with seamed cups and deep bands.
How a nursing bra should fit
- The band is level and firm. Bought in late pregnancy, it fastens on the loosest hook.
- The cup contains you when you are full, with a little spare room after a feed.
- Nothing presses into breast tissue at the sides, underneath or at the top edge.
- With the cup dropped, the sling does not cut across the breast.
- You can undo and redo the clip with one hand.
General fit principles are in how a bra should fit.
Where to buy and be fitted
High-street chains and supermarkets sell nursing bras in the main sizes. Department stores and independent lingerie shops offer maternity fittings, and full-bust retailers cover larger cup sizes. It is worth being fitted in person at around six to eight weeks, once feeding has settled.
Frequently asked questions
What should I look for in a nursing bra?
One-handed clips, a supportive sling that stays in place when the cup is open, a band with at least four rows of hooks, soft breathable fabric, and some stretch in the cup to cope with changes in fullness.
Are wired nursing bras safe?
Many people wear them comfortably. The concern with any bra while feeding is pressure on breast tissue, so a wired nursing bra must fit well and sit on the ribcage. Flexible wires are common in nursing bras. Non-wired styles are usually suggested for the first weeks, when size changes most.
What is the best nursing bra for a large bust?
One sold in band and cup sizes by a full-bust brand, with seamed cups, a full sling, wide straps and a deep band. Stretchy one-size-fits-several styles rarely give enough support above a DD.
