Are you familiar with maternity clothes?
If not, let me enlighten you.
There are two maternity shirt styles: the tent, and the underbust hug. Neither are that attractive. Granted, they are attempting to cover a giant mass of blob, so you can't really blame the limited style selection.
The underbust hug is often accompanied by strings that tie in the back. Or sometimes the front.
My girls love this wardrobe modification.
Yes. Kind of like a dog. A very large, upright, pregnant one.
