Where's the Maternity Clothes?

I've been here a little over a year now and I just noticed something. There are a fair number of pregnant women on the streets, on the busses, in the restaurants. None of them are wearing anything that could be remotely called maternity clothes?

Is it the same now in the US and other countries?

Normal dress is jeans hanging as low on the hips/tush as possible without falling down with a T-shirt, blouse, sweatshirt. The same jeans with a looser top work.

Usually, I'm not out and about when people are going to and from work. Maybe women who work in stores and offices where a more professional style is in order have a different kind of wardrobe.
