Re: Do I really have to buy maternity underwear? What's the difference?
Maternity underwear is usually made to be extra-stretchy and either low-cut, to fit underneath a growing belly, or high-cut, to fit over it. But no, it's not a necessity. You can totally get away with wearing some regular comfy undies, as long as they have plenty of stretch and are low-cut. Just beware that you may have to buy some in a larger size late in the pregnancy. Luckily, it's easy to find soft, durable pairs that are affordable. (Think Hanes!) Look for the microfiber seamless kind--they're lightweight and won't add bulk to your frame.
