Japanese Weekend!

Most of my maternity clothes were this brand, and I LOVED my maternity wardrobe. I hated giving it up after. In fact, I wore some of the clothes for months after.
I knew I was not going to be pregnant again. I was 40 at the time. But like you I wanted to wear nice, comfortable, well-fitting clothes.
