So this one i'm slightly less sure about because of the texture of the main top but it looks like 1965's Photo Fashion top. The Barbie Style version looks more sweater-y whereas the original looked more like a textured fabric.
This is from BarbiePedia, the full outfit Photo Fashion #1648 came with the sweater, matching pants and dickey, heels, and a camera. I don't have this one but I have the Hill Riders' sweater and they both fit modern dolls like the first screenshot here. The sleeve rides up a bit so it looks like a three-quarter sleeve, which I do like a lot, but it looks like the second screenshot has the rolled neckline pulled down in an off the shoulder style and the sleeves look longer. It's a pretty piece and I hope they'll keep using fashions from the early years.
A sized down version of the main outfit was released for Skipper called Outdoor Casuals.
