Frequently Asked Questions (FAQs)

1. What kind of swimsuit should I wear while pregnant?

An actual maternity bikini isn't necessary. It may make sense if you are carrying really low and are having a hard time finding a bikini that both fits under your belly nicely and has good bum coverage. Otherwise, look for a bikini with a supportive halter top and low rise bottoms.

2. Can you wear normal swimwear when pregnant?

Sure, you can get away with wearing one of your regular swimsuits in the early months of your pregnancy. But as you progress, you'll need a suit that caters specifically to a pregnant body. If you prefer separates, opt for a tankini or swim dress top with your regular bottoms.
