Barbie Clothing Id Request - 2 Superstar Era Items

I have two outfits I am trying to find the name for. The first is a dress with red and white horizontal stripes, 3/4 sleeves, gathered at the waist and open in the back. I think I got it between 1978 and 1984, but I am not certain. It has no tags, but I am certain it is genuine Barbie.

The other is a yellow jumpsuit with a halter-type top that ties on the back of the neck. It has purple, orange and red paint sploches on it and a matching jacket. It does not have any tags and I am not sure if it is genuine Barbie or not, but I think it is.

Any help would be most appreciated.
