What do you wear to the beach when pregnant?
It’s totally up to you ‒ some mamas choose to wear maternity swimwear, while others find that their usual swimsuits still fit during the first and second trimesters.
However, there are some things to be aware of when heading to the beach while pregnant:
- Wear something loose over the top of your swimwear to avoid getting sunburn.
- Bring a hat to protect your face, ears, and the top of your head from the sun.
- Wear sunscreen!
- Stay in the shade as much as you can.
- Stay hydrated by drinking plenty of water.
Where can I buy a maternity swimsuit?
There are lots of places you can buy maternity swimwear, take your pick:
What size maternity swimsuit should I buy?
When it comes to maternity swimwear sizing, it depends on how far along you are in your pregnancy and how big your bump and breasts are compared to your pre-pregnancy size.
Most of our Peanut mamas said that up until around week 25, they were able to order maternity bathing suits in their ‘normal’ size, then in their third trimester, they had to order a size up to fit their growing bump.
Are maternity bathing suits necessary?
No, maternity swimsuits aren’t necessary if you’re planning on swimming or chilling poolside while pregnant.
But the key to remember is comfort ‒ you don’t want a swimsuit that’s digging into your baby bump or making your breasts feel smushed.
Usually, maternity bathing suits will allow for a little more room and more support in the boob and bump areas.
Whatever you find comfy, mama.
Can you wear a regular swimsuit while pregnant?
Yes, if you’re comfortable, you can wear a regular swimsuit while pregnant, although as your baby bump grows, you may find that it’s getting a little tight.
Prioritize comfort over style when it comes to maternity swimwear, but if you have a regular swimsuit that’s adjustable, you can try loosening it to see if it will fit.
Is it OK to wear a 2 piece while pregnant?
Yes! You can wear whatever you want while you’re pregnant.
Want to flaunt your bump in a pregnancy bikini? Do it!
Feeling more modest and want to cover up? Do it!
Following in the footsteps of Rihanna’s flawless pregnancy style? Do it!
You do you, mama.
Is it okay to wear a bikini while pregnant?
Yes, it’s more than okay to wear a pregnancy bikini ‒ in fact, some mamas say they’re more comfortable than maternity one-piece swimsuits as they allow more space for your growing bump.
But as with anything in pregnancy, you wear whatever you want to ‒ this is your pregnancy journey, so you can do it however you want!
Can you wear high-waisted bikini bottoms when pregnant?
Yes, you can wear high-waisted maternity bikinis while pregnant.
A lot of pregnancy bikinis come with high-waisted bottoms to provide extra support to your growing bump.
Just make sure they’re not digging into your bump ‒ after all, you should be comfortable.
Can tight bikini hurt baby?
No, wearing a tight bikini or other tight clothes won’t cause any harm to baby, although they might feel uncomfortable for you.
Can I swim while pregnant?
Yes, you certainly can swim while pregnant, if you want to ‒ it’s actually one of the safest and most effective pregnancy workouts you can do!
Swimming while pregnant doesn’t put any pressure on your joints, works all your muscles, and you don’t need any extra equipment to get started ‒ just a body of water and a maternity swimsuit!
Can you snorkel while pregnant?
Yes, you can snorkel while pregnant, too ‒ while scuba-diving while pregnant isn’t recommended, snorkeling is just fine.
As you’re staying fairly close to the surface and since swimming while pregnant is one of the best workouts, you should be fine to snorkel.
However, if you’re at all unsure, it’s best to check with your doctor first.
That’s all there is to know about maternity swimsuits!
