Washing impurity from one's clothing

My dress got soiled with stool and while I was washing it, my dress touched my body/thighs before squeezing the water from my dress. Then I continued washing my dress and squeezed it which means my dress is clean now. But this wet dress touched my body/thighs which became naapaak first and I did not wash it because I wanted to wash my dress first. So now did my dress become naapak again? If yes, so how many times should have I washed it - one time or three times? What if I have washed it only once and wore again and sat, slept, etc. Do I need to purify all the things?
