Putting together summer maternity outfits is not for the weak. Whether it’s nausea, swelling, or sweat coming from places you didn’t know could sweat (elbows?!), we get it.


If you’re pregnant or postpartum and trying to survive the heat, here’s your summer maternity style survival guide — from what to wear to how to stay cool.


When choosing maternity clothes for hot weather, there’s a lot to consider: fabric composition, fit, silhouettes — and your own sense of summer maternity style. Below, we’ll walk you through what to wear when pregnant or postpartum in summer so nothing clings, digs, or turns your bump into a furnace.


And the best part? You don’t have to buy it all. Renting your summer maternity clothes means less panic-buying and more breezy options that actually suit the season.

How to Choose Summer Maternity Outfits

Before you even look at styles, check your labels. You might not realise this but what you wear can matter beyond your style— that's because when you're pregnant, overheating isn’t just uncomfortable, it can be risky.

Look for

  • Breathable and natural fabrics: cotton, linen, silk, and chambray help you stay cool and reduce irritation
  • Loose silhouettes and bump-accommodating fits: allow space for your bump and prevent overheating
  • Armpit-free styles e.g. sleeveless, short-sleeved and cling-free, loose sleeves
  • Easy-access necklines for those breastfeeding or popping a pump in your nursing bra

“With your core temperature rising in pregnancy, you may feel the need to wear the lightest, least constricting clothes possible,” says Sarah Murray, Cambridge Independent Midwife.


And it might not be a bad thing: “Overheating stresses your body, which can impact the baby’s neural development in the first trimester and trigger early contractions in the third. Stay cool — literally.”


While most pregnancies go smoothly even in warm weather, NCT guidance notes that a core body temperature above 39.2 °C during the first trimester can slightly increase the risk of birth defects.


Overheating can also lead to dehydration, heat exhaustion, fainting or heatstroke, which may stress both you and your baby. Severe overheating could potentially trigger early contractions in the third trimester. To keep safe, avoid lengthy stints in the sunshine, sip water frequently and dress for the hot weather.

2. The Minimalist Bump-Friendly Maxi

Maxi dresses aren’t all about loud colours and bold prints (though, we do love those). Pair it back with a simple maxi that you can dress up or down with accessories to be fuss free this summer.

How to Accessorise Without Overheating

Pregnancy in summer = maximum sweat, minimum patience. So skip the fussy accessories and try these instead:

  • Leave tight strappy sandals behind and opt for comfy slider-style sandals instead
  • Sunglasses can hide a multitude of sins and give even the most tired Mama a glamorous bump
  • Don’t sequester natural fabrics to your clothes, consider cotton totes and woven bags as accessories.
  • Protecting heads from the sun isn’t just recommended for children, consider a sunhat or, this year’s mum go-to: a branded cap 

Smart Buys to Survive the Summer Heat

Real Mum, Real Heat

Bridget March Sheikh , mother-of-three, Beauty Director and Consultant, shares her summer survival tips:


“I definitely have increased sensitivity to heat when pregnant, so I avoid synthetic materials and tight fits. Another reason I go loose? I grow throughout the day — water retention is real! Sizing up, even in maternity, helps me feel comfortable.


Linen is my go-to. Long, wafty dresses, belted above the bump, give me shape without the squeeze.


And I love renting maternity wear. It’s sustainable, yes — but also makes me feel like me in that moment. Something unique, something that speaks to the version of me I am right now.”
