Pregnancy outfits can feel like a guessing game, especially when you’re carrying a baby through a blazing summer—and if you’re in Arizona like me, it’s hot most of the year. I was pregnant during the peak of summer 2025, due in July, and by the time I hit my third trimester, I wasn’t dressing for cuteness—I was dressing for survival.
If you’re looking for comfortable summer pregnancy outfits that keep you cool, help you feel like yourself, and actually work when your body is constantly changing, I’ve got you. Here’s what I really wore, what I regretted, and what I’d recommend to any mama sweating her way through the third trimester.

1. Overall Onesies Were My Go-To Pregnancy Outfits
Hands down one of the best pieces I owned. I had a pair of overall onesies in a super soft fabric (shoutout to Free People), and they were perfect for a comfy summer day when I needed room to expand without feeling like I was suffocating.
They were flowy, breathable, and easy to layer with a tank or T-shirt. Bonus? I wore them postpartum too because they made me feel put-together without any effort.
2. Pregnancy Biker Shorts for Everyday Wear
Biker shorts were a pregnancy outfit essential by 30 weeks. I had a few different pairs that stretched comfortably over my belly and kept me from overheating. These were lifesavers on hot errands, long walks, or just lounging around the house with my toddler. I’d throw on an oversized tee and I was good to go.
They’re also great for layering under dresses if you need that extra comfort and coverage. This was a daily staple during summer 2025, and I honestly don’t know how I would’ve made it through without them.
3. I Tried Pregnancy Jeans… and Gave Up Fast
I wanted to like them—I really did. But even the ones designed for pregnancy kept falling down or digging in the wrong places. The elastic didn’t stay up, and they were just too hot for an Arizona summer. By 28 weeks, I was over it.
I wore my pre-pregnancy jeans unbuttoned with a belly band for a while, but once the bump got bigger, they just weren’t worth the effort.
If you’re looking for comfy pregnancy outfits, skip the jeans and thank me later.
4. Empire-Waist Dresses and Babydoll Styles = Breezy and Cute
These were my favorite pregnancy outfits for summer days when I actually wanted to feel cute. Flowy babydoll dresses, empire waistlines, and breathable cotton or rayon fabrics made life a lot easier. I found one floral maxi dress from Amazon that wasn’t technically maternity, but it fit beautifully over my bump and I still wear it today.
Perfect for brunch, errands, or just staying home and trying not to sweat through your couch. If you’re pregnant during summer 2025, grab a couple of these—you won’t regret it.
5. Birkenstocks and Easy Slip-On Shoes Only
Footwear was all about ease and comfort. Birkenstocks were my everyday go-to—supportive enough for errands, easy to slide on, and no straps or buckles to mess with. When your belly’s huge and bending down feels like a core workout, that matters.
If I needed to dress up a bit (like for church), I’d wear a low wedge or small heel. But high heels? Not a chance. I needed comfortable summer footwear that let me actually function.
6. Belly Bands = Secret Weapon for Long Days
Not exactly a pregnancy “outfit,” but worth mentioning. Once I got further along, I started wearing a belly band under my clothes, especially for longer walks or any light activity. It helped reduce back pain and gave me extra support where I needed it most.
Perfect for summer mamas who still want to stay active without feeling totally wiped out afterward.
Wish someone would just hand you a hospital bag packing list? I’ve got you, mama. Here’s the exact one I used with both my babies
7. Soft, Comfy Bras That Actually Fit
My bras stopped fitting somewhere around the second trimester, so I sized up and grabbed a few soft, wireless ones from Aerie. No underwire, no digging, just comfy support that I could wear all day. If your chest is growing fast, make this upgrade early—it’ll save your sanity.
Also worth noting: when it’s 110°F and you’re sweating constantly, anything with lace or extra padding is just too much. Keep it simple and breathable.
8. High-Waisted Skirts and Shorts to Show Off the Bump
These gave me the best of both worlds—bump-friendly and cute. I loved pairing high-waisted skirts with simple tops or oversized button-downs. You can keep it casual or dress it up depending on your plans.
In terms of pregnancy outfits for summer, this combo let me stay cool while still feeling like I had some sense of style.
9. Fitted Dresses (When I Was Feeling Myself)
Some days, I just wanted to feel a little extra. Stretchy bodycon dresses were perfect for that. They hugged the bump in all the right ways and gave me a little confidence boost—great for date nights or quick maternity photos.
Just make sure it’s breathable. A skin-tight dress in the middle of summer can go from cute to suffocating fast.
10. What I Didn’t Wear—and Don’t Miss
Let’s keep it real. Here’s what didn’t work for me:
- Tight tops that clung to everything
- High heels (way too much pressure on swollen feet)
- Complicated layers or structured outfits
- Thick jeans or stiff fabrics
Toward the end of my pregnancy, I even started wearing my husband’s shirts. I went into labor with my first baby literally wearing one of his oversized tees. Nothing else felt good, and it was just too hot. Pregnancy outfits don’t need to be fancy—they need to work.
Final Thoughts: Your Pregnancy Outfits Should Work for You
If you’re pregnant during summer 2025, give yourself permission to dress for comfort. Forget the perfectly curated maternity wardrobe or what Instagram says you need. You need breathable, comfy, stretchy pieces that make you feel good—whether you’re heading out the door or just trying to survive another day of third trimester exhaustion.
Stick with a few key comfortable summer staples: biker shorts, flowy dresses, slip-on shoes, and some well-fitting bras. Mix in a belly band for support, high-waisted bottoms when you want to style the bump, and skip anything that makes you feel restricted or overheated.
You’re growing a human. And in 100+ degree heat, that’s more than enough. So wear what works, ditch what doesn’t, and don’t be afraid to repeat the same outfit five days in a row. (I did.)
