Target has some T-shirts that I’m loving right now. super soft and long tshirt
I ordered my maternity jeans from amazon using prime wardrobe but they are also available to regular purchase. I tried 4 different pairs from 3 different places (old navy, motherhood maternity, and the Levi’s from amazon) and the Levi are definitely my favorite. They fit perfect, have good stretch to them and don’t gap or show butt crack. I didn’t have much of a baby bump until week 19-20 but I started having trouble getting my jeans to be comfortable through the day a few weeks before. The Levi have an elastic band instead of a traditional denim waistband or an over the bump spandex band. They were much more comfortable for me to wear at an earlier period.
Best of luck in your search!
