Fictional 27-year-old woman, glossy black hair in long polished waves over one shoulder, smooth warm skin, polished makeup with defined brows and a confident direct gaze; slate-blue satin corset lingerie set with ice-white lace trim and a sheer pale-grey robe slipped off one shoulder, standing in a slate-blue room beside a wooden stand holding one polished brass sextant, the instrument completely plain with no engraved brand, scale letters, numerals or lettering anywhere, cool bright window light, all surfaces completely plain, no text anywhere, editorial photograph, photorealistic, no text, no words, no letters, no numbers, no logos, no watermark
