I am watching season 1 and in several episodes Cindy is wearing the same green sweatshirt and greeh hair ribbons.

I don't notice the other kids wearing the same thing over and over again. Anybody know why this is?

Did they need to shoot Cindy in several scenes at once and they just kept her in the same clothes?

Watch a little closer. Greg has a blue/gray t-shirt with a dark circle around the neck that he wears frequently in seasons 2/3. He also has this shirt that zips up the front with a round circle for a zipper pull that shows up pretty often. Carol has this ugly, shiny red/white checked blouse that she wears a lot in the mid-series episodes.

In the later seasons, Greg has this silly looking large striped, black and white, tight fitting shirt that he wears a lot. Also in the later seasons, Peter has a sort of black, yellow and white short sleeved shirt that he wears a lot. It was when both Greg and Peter had perms.
