On this shirt I added a piece of black knit fabric to raise the neck line to a less revealing level . I also added some elastic to the sides (see below). The shirt seemed a little too tent-like, so I thought adding elastic on the sides would bring it in and make it a little more fitting. It looks okay, I probably should have used smaller elastic, and I ended up having to use two pieces because it wasn't gathered enough.
This last shirt had a collar, which would make you think there would be buttons, but it was wide open. Why do they make every maternity shirt low cut? Back to the shirt. I tried to sew button holes, but the fabric was too thick, so I just sewed it closed and then hand sewed three buttons on it. I think it looks good now. I have one more shirt that needs this button treatment, but I was tired of hand sewing buttons, it's my least favorite thing to do!
