Dionne says to keep these things in mind when you invest in your pregnancy wardrobe:

This coat is the ultimate in versatility. It has an insert that allows for your bump to grow, and acts like a pouch to carry your baby. Once you've delivered, zip out the insert to fit your body post-baby.
Also, a must-have while pregnant is a great pair of jeans — not your 'mom' jeans. These are slightly distressed and more fitted to the body.

You don't have to sacrifice style with this fabulous printed jersey dress that grows with you. A black blazer is another great staple that can be paired with jeans and a lot of other pieces in your closet.

The little black dress hits all the rules. We all need one in our regular wardrobe, and pregnancy is no exception. It's so easy to dress up or down by changing your shoes and accessories.
