A Dress Crosses the Seasons

Generate exactly one original conceptual fashion photograph, portrait 4:5, text only with no reference pixels. An original adult woman walks through one tall freestanding doorway in an open courtyard. On the near side it is dry late summer, and her long flowing dress is lightweight saffron silk; beyond the doorway it is snowy winter, and the same continuous trailing fabric becomes dense cream wool exactly where it crosses the threshold. She lifts the front hem to step over a small snowdrift, with one bare hand and face clearly visible. Frame the cloth's material transition prominently, keeping seam direction continuous. Crisp overcast daylight, restrained stone architecture, natural motion and anatomy. No words, brands, celebrity likeness or watermark.
