Arse about face

I can only see the back-side,
Bent over in the street.
A gigantic light bulb,
In cloudy white leggings.

My attention, drawers out to,
The gusset pressing through, grey,
Unashamedly to the world.
The torso is slumped over,
The bar of a buggy.

Attired; acrylic jumper,
Bare ankles, clumsy buckled shoes.
I pass, and look down on,
Then up to the laughing baby.
