Much like the regular Gap store, Gap Maternity (found at most Baby Gap retailers) is a good place to get your wardrobe staples. The quality is typical Gap (good, but not great) and you will spend a bit more than places like Target, but the items will last you longer. They have a great selection of affordable jeans, with different size waistbands as well as a nice variety of basic tops (tanks, button downs, etc). Check out their online store for a great selection of nursing bras. If something isn’t on sale, come back in a few weeks, and it is sure to be!
