Stylish/put together moms - how do you do it?

My baby is 9 months old, so definitely not a newborn but every time I leave the house I'm dressed in the first thing I managed to grab from the closet, my hair is a mess (at least I try to wash it often), makeup non-existent (I consider it a success when I manage to put on mascara). None of my clothes fit anymore, nursing clothes are an ugly, overpriced, low quality joke. Even if I somehow managed to put something nicer on within minutes it's covered in baby food and when we go out I will get sweaty within 5 minutes from carrying all the baby gear down the stairs. I won't even mention my nails, which did not see a salon in a year.

And then I go out and see thin moms in full make up, pretty clothes, nice hair (and clearly regularly dyed), often with equally stylish babies... I have a cousin with two kids, one about the same age as mine, she always looks like model. How do you guys do it? How is it possible, do you have some magical room where you put your babies in and they patiently wait for half an hour while you put your pretty on? What kind of witchcraft is this?
