There's no exact science as to when you should start wearing maternity clothes. As every woman's body changes differently, you may not know when you need maternity clothing until your regular wardrobe starts feeling snug. A maternity band is a great piece to take you from the early stages of pregnancy to the end. It offers support for your growing belly, while giving you the coverage you may need as you transition from your regular clothes. Keep in mind that all maternity clothing sold on BestBuy.ca is designed to fit throughout pregnancy and after, so it's never too early (or late) to start stocking up on cute maternity tops, chic maternity dresses, and belly-hugging maternity bottoms.
The advantages of under the bump are that they aren't so bulky under tops and to combat exposure or to allow you to wear a shorter top you can always wear a belly band or long vest top under your top top. Under the bump tend to work better for skinny, stretchy style jeans as the stretch in the denim will hold the jeans on your leg as supposed to having to rely on the waist band only.
