2. Can you wear a regular swimsuit while pregnant?

Keltner de Valle says, "I never bought any maternity swimwear, and I don't think it's necessary. I liked wearing a bikini so there was nothing restricting on my belly. Also, a bikini is adaptable to a growing belly. String bikinis in particular are adjustable, so they work well when you're pregnant.

3. Should I size up or down for one piece swimsuit?

“Swim fabrics stretch a bit when wet, so sizing down or staying true to size is better when you're spending most of your time in actual water,” she says. “If you're staying dry most of the time, sizing up could help you feel more comfortable since the natural stretching won't happen when the suit stays dry.
