Compose a vintage-style portrait highlighting the side profile of an androgynously beautiful woman with gentle, classic contours. Her face, softly lit to enhance her smooth silhouette and graceful lines, radiates a nostalgic beauty reminiscent of the golden age of portrait photography. She gazes serenely into the distance, exuding a quiet confidence. Delicate flowers in sepia tones gently surround her profile, their presence both unassuming and integral to the composition. The image should employ a soft focus technique, creating an atmospheric, slightly grainy texture that enhances the vintage feel. Capture the subtle interplay of light and shadow, drawing the viewer into a timeless moment that resonates with a sense of classic, enduring beauty.
