Jennifer Love Hewitt! No!
Jennifer Love Hewitt. Girl. What are you even thinking? Are you taking maternitywear pointers from Kim Kardashian or someone? Because aside from her, the only other pregnant woman who ever dared to wear The Most Horrible of Horrible Maternity Clothing was Jessica Simpson, and I don't think even she would like this weird, uncomfortable-looking leather frock.
Sweetie, you're probably the most adorable pregnant woman to ever exist, and it's due in part to the fact that you've wanted this for so, so long. Bearing that in mind, why don't you make the most of it on the fashion end of the hosue? This is something you're going to want to look back on with happiness and comfort and pride, and this ... this vest thing just doesn't quite fit into any of those categories. Man.
Hope you're well otherwise!
