Monochrome Fashion Bun Portrait

Create an ultra-realistic cinematic black-and-white fashion portrait that matches the reference image as closely as possible.

HAIRSTYLE — VERY IMPORTANT:
Recreate the SAME hairstyle as the reference:
{argument name="hairstyle" default="dark long hair pulled into a messy, elegant low/high bun at the back"}, with natural loose strands framing both sides of the face and a few soft strands falling around the forehead and cheeks. Hair should have the same volume, texture, messy-but-elegant styling, and overall silhouette as the reference image.
Do not use straight loose hair. The bun hairstyle must be clearly visible and closely match the reference.

POSE:
Match the reference pose extremely closely.
Chest-up to waist-up portrait.
Body facing mostly forward.
Head turned slightly toward the RIGHT side of the image.
Face looking toward the right, NOT directly at the camera.
Confident, serious, composed expression.
Chin slightly raised.
Shoulders relaxed and naturally positioned.
Both hands placed inside the blazer pockets, exactly like the reference.
Recreate the same elegant confident fashion-model posture.

OUTFIT — MATCH THE REFERENCE:
Wear the same style of clothing:
a sophisticated tailored black blazer with structured shoulders,
black satin/silk-like button-up shirt underneath,
shirt slightly open at the collar,
no tie,
all-black luxury executive fashion styling.
The blazer should have the same cut, lapels, button placement, pocket details, and overall silhouette as the reference.
Keep the outfit modest, elegant, fully covered, and professional.

SUNGLASSES:
Add the same style of {argument name="sunglasses" default="black sunglasses"} as the reference image.
Dark matte/black sunglasses with a similar rectangular/cat-eye shape, size, position, and angle.
The sunglasses must sit naturally on MY face without changing my facial proportions.

BLACK-AND-WHITE STYLE:
Pure cinematic monochrome black-and-white photography.
Deep blacks, rich grayscale tones, strong contrast, realistic skin texture, dramatic shadows, premium luxury editorial photography.

LIGHTING — VERY IMPORTANT:
Recreate the distinctive lighting from the reference image.
