Maternity clothes are designed in places with a winter. That's the whole problem in one sentence. The jersey is thick because it holds a shape under a coat, the panels are doubled over the bump, and the whole thing is built for a heated room at 20 degrees.
Put that on in Singapore in the afternoon and you'll be soaked through by the time you reach the MRT.
Fabric first, because it decides everything else
I design clothing for a living, so this is the part I can be exact about. Two properties matter here and they aren't the same thing. The first is whether the fabric lets moisture off your skin. The second is whether air can move through the weave. A fabric can do one and not the other, and most maternity jersey does neither.
Cotton voile, cotton lawn, linen, rayon and bamboo viscose all move moisture and breathe. Polyester and its blends hold both the heat and the damp against you, and they're everywhere in the maternity aisle because they keep their shape through a lot of stretching and cost very little to make.
The test in the shop takes four seconds. Hold the fabric up to the light. If you can see the weave, air moves through it. Then bunch it in your fist and let go. Fabric that springs back with a slight warmth in your palm is holding heat and will do the same across your whole back.
What to buy, and what not to
Very little, since a bump changes shape for about five months and then stops needing any of it.
- Two pairs of trousers or a skirt with a proper over-bump panel, in linen or a light rayon. The under-bump versions roll down and dig in when you sit.
- Three loose tops you'd wear anyway, sized up, in a woven fabric, not jersey.
- One dress that can be worn to something formal, because the invitation always arrives in month eight.
- A stretchy band to extend the button on your own trousers, which costs a few dollars and covers the whole second trimester.
Skip the maternity bras until after the birth. Skip anything with a thick doubled panel over the stomach. Skip the whole idea of a maternity work wardrobe if your own clothes have any give in them.
The rest of the pregnancy set
Dressing modestly at 32 degrees
This section exists because nobody writes it and a great many women here need it. Covering arms, legs and hair in this heat while pregnant is a real engineering problem. The answer is in the fabric and the cut, not in wearing less.
For a baju kurung or an abaya, cotton voile or a light rayon in a loose cut moves air across the skin as you walk, which a fitted synthetic can't do at any weight. The looser the cut, the cooler it is, and that runs opposite to the instinct that more fabric means more heat.
For a hijab, the fabric against the scalp and neck is the part that counts, since that's where you lose heat. Cotton voile and bamboo jersey both manage it. Chiffon and satin, which drape beautifully, sit against the skin without letting anything through. A cotton inner cap under a lighter outer layer is what most people I've asked have settled on.
One thing I'd add from the construction side. Look at where the seams fall. A seam across the small of the back under a waistband is a hot spot at any weight of fabric, and so is one at the shoulder under a bag strap. In the third trimester that's where the prickly heat starts.
The afternoon problem
Between eleven and four you cross from a 22-degree office to a 32-degree street several times, and no single outfit is right for both. The answer is a layer you take off at the door, not a fabric that compromises between them. A thin cardigan in the bag, and everything underneath chosen for the street.
I wore the same four things for most of my second pregnancy and photographed very few of them. I don't think I'd change that, though I might have bought the linen trousers in month four instead of month seven.
What other parents wanted to know
What fabrics are coolest for maternity wear in Singapore?
Cotton voile, cotton lawn, linen, rayon and bamboo viscose. All of them move moisture off the skin and let air through the weave. Polyester and polyester blends hold both heat and damp against you.
How much maternity clothing do I need?
Two bottoms with an over-bump panel, three loose woven tops sized up, one dress for a formal occasion, and a button extender for your own trousers. A bump changes shape for about five months, so a large wardrobe is rarely used.
How do I dress modestly in this heat while pregnant?
Keep the cut loose and choose cotton voile or a light rayon, since a loose garment moves air over the skin as you walk. For a hijab, the layer against the scalp and neck matters most, so cotton voile or bamboo jersey over a cotton inner cap works better than chiffon or satin.
