The 8 best cotton nursing bras on Amazon

Most nursing bras are made of synthetic material that can be very good quality and feel great on the skin.

But let’s not forget good old cotton. Environmental benefits aside, cotton nursing bras feel baby-soft on sore nipples and tender breasts. They are also absorbent and breathable, reducing your risk of irritation and rash.

Plus, there are some really good quality yet affordable cotton nursing bras on the market. Check these out:

Best overall cotton nursing bra: Kindred Bravely Extra Soft Organic Cotton Nursing Bra

Why I like the KB Extra Soft Organic Cotton Nursing Bra

  • It ticks all the right boxes – it’s comfy, supportive and affordable.
  • It’s made of organic cotton, which is much better for the environment and for your skin.
  • It’s a pull-on style with no hooks or snaps to irritate your skin
  • It comes in a great range of sizes, catering for moms with size 30B boobs and upwards. It even comes in busty sizes for larger-breasted moms.
  • Comes in 6 pretty colors
  • No wonder more than 1000 moms have given it 5-stars on Amazon.

What I don’t like about it

  • It can lose elasticity if not washed properly – make sure you wash it in a lingerie bag on delicate cycle.
  • Not supportive enough for outside wear.

Why I love the HOTmilk Show Off Nursing Bra

What I don’t like about it

  • not all bras in the Show Off range is made of cotton – only the ivory bra, persian leopard print bra (pic above) and navy bra is made of 100% cotton.
  • full cups come up quite high, this bra is more suited to moms with larger breasts

What I don’t like about it

  • The models don’t look like they have ever been pregnant
  • It’s too stretchy and not supportive enough. If you have large breasts, don’t buy this
  • The lace lining can be scratchy and irritating.
  • If you can afford it, choose a better quality nursing bra even if it costs a bit more. You won’t regret spending the extra money.
