Frequently Asked Questions (FAQs)

1. Can you wear a normal bikini when pregnant?

In your first trimester, you may be able to wear an ordinary bikini that ties at the side. You can tie the knots a little looser as your bump starts to grow. Choose a bikini with built-in support. Or if you have large breasts, it may be worth having a professional fitting for a fitted bikini top instead.
