Your jeans don't button. Your favourite jumper is suddenly too tight across the bust. Or maybe you're three weeks postnatal, still in maternity leggings, and starting to wonder when (or if) any of it ends.
This is a practical, no-fuss guide to building a maternity wardrobe for New Zealand mums that carries you from your first "these don't fit" moment to the postnatal months.
Before you start: the capsule mindset
- Buy on demand, not in advance.
- Choose pieces that work in two trimesters.
- Get the basics right first.
- Borrow before buying.
The full ChicMama maternity range is in the I'm Pregnant collection. The postnatal essentials sit in I'm Postnatal.
First trimester (weeks 0–13)
Most of your existing clothes still fit. A soft non-wired bra is the only first-trimester purchase most mums actually need.
Second trimester (weeks 14–26)
This is when maternity dressing actually starts. Also when most mums buy their first nursing bra.
The four pieces you'll wear most
1. Over-bump maternity leggings. The ChicFlex™ High-Waist Maternity Leggings for everyday wear, and the ChicFleece™ Over-Bump Maternity Leggings for cooler NZ winters.
2. A maternity dress. The ChicDress™ Sleeveless Maternity Dress.
3. A belly support band. The ChicBelly™ 3-in-1 Band.
4. Two soft tops. Stretchy, breathable.
Third trimester (weeks 27–40)
- ChicStripe™ Active Maternity Leggings.
- ChicWaist™ Adjustable Belly & Back Band.
- ChicLounge™ Nursing Pyjama Set.
- ChicVest™ Nursing Camisole.
Postnatal weeks 0–6
- Over-bump leggings still work postnatally.
- Nursing bras come into their own.
- Maternity dresses do double duty.
- The ChicSupport™ Adjustable High-Waist Underwear for recovery.
