Early on, I padded my top. Took them out only to take a shower (even slept in them and a bra). Then boobs came in. They went away.
At the insistence of a person I was working for, I did pad my hips for a short while -- about three months. I liked the way it looked in the mirror after clothed, but wasn't real happy with it overall -- too much trouble.
So I tend to only think of padding as the hip things -- what is often called "body" in street terms.
So only about three months, starting about four months after I went full time.
What I did start doing was buying clothing that fit my body shape overall in a manner to accentuate what I did have (boobs and legs and some butt), and disguise what I lacked (hips and waist).
For some dresses, I have a waist cincher. Because I get bloated, and I got tired of being asked when I was due or how far along I was.
Insofar as suggestions of what to do starting out, I say do whatever makes you most comfortable. I *had* to have the boobs in -- they relieved some of the stress I would feel otherwise. The padding just made me itch and didn't have much to do with how others saw me or how I saw myself.
