Maternity and nursing clothes In-depth guide

Maternity clothes – the complete guide

You wear maternity clothes for a few months, but every day. You don’t need many; you need to choose them well. This guide takes you through what is worth having, when to buy it, and how to spot the pieces that will still work after the birth, for breastfeeding.

The essentials first

  • Don’t buy everything at once. Your body changes gradually, and differently for every woman. What fits at 16 weeks may not fit at 36.
  • Look for pieces that grow with you: soft waistbands, ruching at the sides, a longer front panel, stretchy fabrics.
  • Think ahead to breastfeeding. A top that opens will be useful for months after the birth.
  • Choose the size from the maker’s chart. Many maternity brands work with your normal size, but not all.
  • Comfort comes before “bump-friendly design”. Nothing should dig in under your bump or on your breasts.3

What comes when

Trimesters are counted from the first day of your last period. The first runs to week 12, the second from week 13 to 27 and the third from week 28 to the birth.2 For your wardrobe this is a useful map, even though every body goes at its own pace.

PeriodWhat usually changesWhat is worth sorting out
1st trimester (to week 12)tender, bigger breasts, bloating; in a first pregnancy the bump often doesn’t show yet1a soft bra without pressure, looser everyday pieces, trousers with a stretchy waistband
2nd trimester (weeks 13–27)the bump starts to show, your waist and hips changeyour first maternity leggings or trousers, longer tops, one dress
3rd trimester (from week 28)the bump grows fastest, your legs may swelllayers that unzip, a coat or an insert, a nightdress for the maternity hospital
The postnatal weeks (šestonedelie) and breastfeedingyour tummy shrinks gradually, your breasts change in size through the daynursing tops, soft trousers, nursing bras

We write more about timing in the article When to start wearing maternity clothes.

A small wardrobe that covers most days

This is a sensible base for everyday life. Adjust it to whether you work in an office, at home or outdoors, and to the season.

Everything else is extra. If you love dresses, flip the ratio. If you live in trousers, get two pairs and skip the skirt.

Sizes: how not to get lost

Maternity clothes are most often sold in the same sizes as ordinary clothes (XS to XL, or numbers), with the room for the bump already in the cut. In practice this means:

  • Choose by your bust and hip measurements from the maker’s chart, not by “how much weight you have put on”. The European size designation system is based on body measurements in centimetres.4
  • For trousers and leggings, hip measurement and leg length decide; the waistband of maternity styles is adjustable or stretchy.
  • For tops, watch the length at the front. A top that is long enough at 20 weeks may be short at 35.
  • If you are between two sizes, the smaller one usually pays off in stretchy fabrics, the larger one in firm ones (denim, coats).

Fabrics

FabricWhere it works wellWhat to bear in mind
Cotton with elastanetops, leggings, trousersholds its shape and breathes; the more elastane, the better it springs back
Viscose, modaldresses, soft tops, nightdressesdrapes nicely and feels cool; some types stretch out in the wash
Merino woolbase layers for winterwarm even when damp, smells less; fine grades don’t itch
Polyester, polyamideleggings, sportswear, coat fillingsdries quickly and is hard-wearing, but breathes less in the heat
Softshellcoats and inserts for spring and autumnkeeps the wind out; in frost you need another layer
Fleece, brushed backslined leggings, hoodieseven a thin layer is warm; you may overheat when active in the warm

What to look for in the cut

  • Waistband: soft and wide, one that doesn’t dig in. We explain the types of waistband in the article on maternity leggings.
  • Ruching at the sides of tops and dresses, so the fabric has room to grow.
  • A longer front panel, so the top doesn’t ride up over the bump.
  • Breastfeeding access on tops, if you want to wear them after the birth as well. You will find an overview of the designs in the guide Clothes for breastfeeding.
  • A zip or buttons at the front on warm layers. In the third trimester, pulling a thick jumper over your head gets tiresome.

What often isn’t worth it

  • Lots of items for one stage. Clothes for the third trimester only get a few weeks of wear.
  • Tight shapewear and under-bump belts that dig in. If your doctor recommends a support belt, follow their advice.
  • Bras that dig in. A tight bra or clothing can contribute to a blocked milk duct when breastfeeding; the NHS recommends a bra that doesn’t squash the breasts.3
  • Buying “for the next size up” a long way ahead. Breasts and bump both change unpredictably.

How long you will use it

ItemDuring pregnancyAfter the birth
Leggings with an over-bump panelfrom the 2nd trimester until the birththe first weeks, while your tummy shrinks
Trousers with an under-bump waistbandfrom the 2nd trimesteroften in the postnatal weeks too

A dress that opensthe whole pregnancybreastfeeding, as long as it fits across the bust

The pieces that last longest are the ones that combine pregnancy, breastfeeding and babywearing. That is why Karkulka has separate sections on clothes for breastfeeding and babywearing clothes.

Second-hand, borrowed, altered

Maternity clothes are worn for only a short time, so second-hand ones are often in good condition. Check the stretch of the waistband (whether it springs back after being pulled), the seams around the panel and any bobbling on the inner thighs. When it comes to bras and knickers, most women prefer new.

Ordinary clothes can be stretched for a while: a hair tie through the buttonhole of your jeans, a longer vest under a shirt, your partner’s hoodie. For the third trimester, though, this is usually not enough.

Washing and care

  • Wash items with elastane at lower temperatures and don’t tumble-dry them unless the label allows it; heat makes elastane lose its stretch.
  • Wash viscose and modal gently and dry them in shape.
  • If you plan to wear pieces after the birth too, remember they will be washed more often (milk, sick). Choose fabrics that can take it.

Frequently asked questions

What size of maternity clothes should I buy?

Maternity cuts are usually designed so that you choose your normal pre-pregnancy size, with room for the bump already built into the cut. This is not a rule for every brand, though, so always check the particular maker’s size chart and the measurements in centimetres.

How many maternity clothes do I really need?

It depends on what you wear for work and how often you do the washing. Many women manage with a small wardrobe of around two bottoms, three to five tops, one warm layer and a suitable bra. The rest can be made up with ordinary clothes in a looser cut.

Can I wear maternity clothes after the birth?

Yes, especially pieces that open for breastfeeding and trousers with a soft waistband. In the first weeks after the birth your tummy shrinks gradually, so maternity trousers and dresses are often comfortable in the postnatal weeks too.
