Disco Friends Reunion Comparison

A snapshot of three beautiful friends, then aged 25 (each about 165cm tall), who were dancing on a disco 'podium' in {argument name="past year" default="1991"}, reuniting 35 years later in {argument name="present year" default="2026"} at a special 'Classic Night' disco when they have turned 60.

The generated image should have a 3:4 vertical aspect ratio, composed of two vertical halves in one PNG file, with the top half representing {argument name="past year" default="1991"} and the bottom half {argument name="present year" default="2026"}.
Small text labels '{argument name="past year" default="1991"}' in the top-right of the upper half and '{argument name="present year" default="2026"}' in the top-right of the lower half should be clearly visible in a color that stands out from the background (like yellow or lime green).

[Important Points]
The outfits of the three women (bodycon dresses and high heels) and accessories like feather fans must be identical between {argument name="past year" default="1991"} and {argument name="present year" default="2026"}.
While the bodycon dresses differ in design and color for each individual, each woman must be wearing the exact same outfit in both time periods.
In the {argument name="past year" default="1991"} image, they should appear youthful at age 25; in the {argument name="present year" default="2026"} image, they should appear fuller-figured at age 60.
This is a standing snapshot, not a photo of them dancing on the podium.
Their poses should be almost identical in both time frames.
The background stage design and other people dancing in the background should differ between {argument name="past year" default="1991"} and {argument name="present year" default="2026"}, reflecting the passage of 35 years.
The {argument name="past year" default="1991"} image should be slightly out of focus, with the atmosphere of an old film photograph.
