Big knickers. Soft waistbands. Absolutely no time for uncomfortable underwear.
You've thought about what your baby will wear home from hospital. The tiny sleepsuit. The matching hat. Possibly an outfit so small it doesn't look like it belongs to an actual human.
But what about you?
Because after giving birth, your underwear requirements are going to look a little different.
Whether you've had a vaginal birth or a C-section, your body's recovering. There may be swelling, stitches, a healing incision and several weeks of postpartum bleeding to contend with.
And suddenly, those tiny lace knickers at the back of your drawer aren't looking particularly appealing.
So, what actually makes the best postpartum underwear?
Let's get into it.
What underwear should you wear after giving birth?
The short answer? Whatever feels comfortable, stays in place and works with the postpartum protection you need.
But there are a few things worth looking for.
- Soft, breathable fabrics. Your skin may be more sensitive than usual, particularly if you're recovering from stitches or swelling.
- A comfortable waistband. The last thing you need is elastic digging into your stomach or rubbing against a healing C-section incision.
- Enough coverage for maternity pads. Postpartum bleeding can be heavier than a period, so you'll want underwear that comfortably holds a larger pad in place.
- A fit that doesn't feel restrictive. Your body is still changing after birth. This is not the moment to squeeze yourself into something uncomfortable.
And perhaps most importantly, don't worry about what size is on the label.
Comfort wins. Every time.
1. High-waisted knickers: the postpartum favourite
There's a reason high-waisted underwear is so popular after giving birth.
It offers plenty of coverage, sits comfortably over your stomach and can feel more supportive than low-rise styles.
For anyone recovering from a C-section, a higher waistband may also help avoid rubbing directly against the incision.
Look for soft, stretchy fabrics and waistbands that don't dig in.
And don't be afraid to size up if that feels better.
Your pre-pregnancy underwear size isn't a deadline you need to meet.
2. Cotton knickers: soft, breathable and practical
Sometimes the simplest option is the best one.
Soft cotton underwear can be a comfortable choice during postpartum recovery, particularly if your skin is sensitive.
Breathable fabrics and a relaxed fit can help reduce rubbing, while full-coverage styles are useful for keeping maternity pads securely in place.
It's worth having several pairs ready before birth, especially if you expect to be changing your underwear more frequently than usual.
And if you're packing your hospital bag, we'd recommend prioritising comfort over anything remotely glamorous.
There'll be time for the fancy pants later.
3. Disposable maternity underwear: useful for the early days
Disposable maternity knickers are another option worth considering, particularly immediately after birth.
They're designed for short-term use and can be useful when postpartum bleeding is at its heaviest.
Some styles have built-in absorbency, while others are designed to hold a maternity pad.
They're convenient, especially in hospital, although you'll need to check whether a particular product is suitable for your bleeding and how frequently it should be changed.
If you prefer reusable underwear, you can also choose comfortable full-coverage knickers with dedicated maternity pads.
It's really about finding what works for you.
4. Postpartum period pants: reusable comfort for the weeks after
Once postpartum bleeding becomes lighter, period pants can be a brilliant addition to your underwear drawer.
They're designed with built-in absorbency, making them a reusable option for managing menstrual blood and, when appropriate, lighter postpartum bleeding.
And unlike disposable maternity underwear, you can continue using them when your periods return.
Our Mooncup High Waist Period Pants are soft, stretchy and designed with a comfortable high-waisted fit.
They offer absorbency for up to 10 tampons' worth of blood, with built-in protection that moves with you.
No bulky pad. No wings. Just comfortable, reusable protection.
One important thing: In the earliest days after birth, maternity pads are generally recommended because postpartum bleeding can be particularly heavy and healthcare professionals may need to monitor your blood loss.
As your bleeding settles, period pants may become a suitable option depending on your flow and recovery.
What underwear is best after a C-section?
If you've had a caesarean, your underwear needs a little extra consideration.
Your incision will be healing, and the surrounding area may feel tender or sensitive.
High-waisted knickers can be particularly useful because the waistband sits above the incision rather than directly across it.
Look for soft fabrics, gentle elastic and a fit that doesn't put pressure on your wound.
Avoid anything that rubs, digs in or causes discomfort.
And remember, you'll still experience postpartum bleeding after a C-section, so you'll need underwear that works with maternity pads, too.
For more information on healing after abdominal birth, take a look at the NHS guide to caesarean recovery.
What underwear is best after a vaginal birth?
After a vaginal birth, you might experience swelling, tenderness or stitches around your perineum.
So softness is going to be your friend.
Full-coverage cotton knickers with a comfortable fit are a good starting point, particularly when paired with maternity pads.
Avoid underwear that feels tight around your vulva or puts pressure on sensitive areas.
And because postpartum bleeding can last for several weeks, having enough comfortable pairs to rotate through is a good idea.
If you have stitches, follow your midwife's advice on keeping the area clean and caring for your recovery.
The NHS guide to your body after birth has more information on perineal care and healing.
How many pairs of postpartum underwear do you need?
There's no magic number, but we'd recommend having a few more pairs than you usually would.
The NHS suggests packing five or six pairs of knickers in your hospital bag.
Full-coverage styles that comfortably hold maternity pads are particularly useful, and it's worth having a few extras ready at home.
Postpartum bleeding can be unpredictable, and leaks happen.
Having clean, comfortable underwear within easy reach means one less thing to think about.
See the NHS hospital bag checklist.
When can you start wearing period pants after giving birth?
There's no single date that works for everyone.
Postpartum bleeding, known as lochia, is usually heaviest immediately after birth and gradually becomes lighter over the following weeks.
During those early days, dedicated maternity pads are generally the best starting point.
Once your bleeding has reduced and you're comfortable using period pants, they can offer a reusable alternative for lighter flow.
Just make sure the absorbency is suitable for your needs, and continue to monitor your bleeding.
If you're experiencing sudden, very heavy bleeding, particularly with dizziness or faintness, seek emergency medical help.

Big knickers. Bigger priorities.
The best underwear after giving birth isn't necessarily the prettiest, the smallest or the most expensive.
It's the underwear that feels good on your body, works with your recovery and gives you one less thing to think about.
Whether that's soft cotton knickers, disposable maternity underwear or a pair of high-waisted period pants, there's no one-size-fits-all answer.
And there certainly isn't a prize for getting back into your old underwear the fastest.
Care for the fourth. Because birth isn't where the care stops.
