I had 4 of these V-neck tees when I was pregnant. They were some of my favorite maternity clothes. There isn't anything fancy about them. They are just what they sound like - short sleeve v-neck tee shirts.
I was still teaching when I was pregnant and I picked these up because they were nice enough to wear to work and I could wear them with anything. I didn't want to spend a lot on clothes I would only wear for a few months and I wanted things that I could get a lot of wear out of. These shirts come in lots of different colors (mine were white, black, pink, and coral). They are soft and stretchy and really grow with you. I wore mine from the time I started showing right up until the end of my pregnancy. I admit that in those last few weeks, about an inch of belly showed when I wore them, but at that point I didn't care.
I even wore these the first few months I was nursing. I just pulled the neck down to nurse and they worked great. The ones I wore the most for this are stretched out at the neck, but that's my fault.
Overall, these tees held up very well. The colors didn't fade and the fabric didn't ball up after many washings. I really recommend Motherhood Maternity for casual tee shirts. They'll last through your pregnancy and you don't have to spend a fortune on them.
