First of, you should know that you will not need maternity clothes right away. After all, it will take time for your belly to grow, and for the rest of your body to change in preparation for both the pregnancy and the birth. In other words, there is no need to go shopping for maternity clothes the moment you find out about the pregnancy. Give yourself and your partner time to digest the news before you redo your closet.

You will know when you need to widen your wardrobe (usually closer to the end of the first trimester if not later). When you (and your changing body) are ready to shop for maternity clothes, you want to take a minute before running to the store and look at yourself in the mirror.

Consider the fact that your body will go through a series of changes – it will both expand and contract again and so you will want a wardrobe that can keep with all these changes.  Therefore, keep in mind that you will be wearing your maternity clothes while you are pregnant AND for a while after you give birth.

Considering all these changes you want to look for maternity clothes of a good quality, which will retain their elasticity and still look good as you return to your pre-pregnancy shape. If you are planning to breastfeed, it will also be smart to plan ahead and buy maternity tops and dresses that are also designed for discreet nursing.

In all likelihood, you will be in your maternity clothes for about nine months to a year, and you may need two different sizes (one for earlier in the pregnancy and later after the birth, the other for your last trimester and right after the birth). So plan accordingly when you start expanding your wardrobe.
