You know what really grinds my gears? When stores take a skinny model, straps a belly on her, and calls it maternity. Cause no. Your body changes in so many ways; it's not like stuffing a pillow under your shirt. Like I said in my what not to wear during your pregnancy post, your hips, chest, and bust all expand along with your waist disappearing and belly ballooning.
It just irritates me because it's frankly lazy. A picture of a model with a fake belly on doesn't fulfill it's purpose of showing you what the garment will look like on a body that is actually pregnant.
