Portrait surréaliste d’une noble femme en robe de poussière d’étoiles

Create a surreal oil painting of a noble woman wearing a gown made of stardust. The dress should look like a deep space nebula with swirling galaxies and glowing stars woven into the fabric. Use heavy impasto brushstrokes to create thick texture on the canvas. The lady has a dreamy, distant look in her eyes. Set her against a dark, void-like background to make the dress pop. Mix soft blending with sharp, bright highlights of gold and violet. The lighting should seem to come from the dress itself, casting a soft glow on her face. Blend classic portrait styles with dream-like, impossible physics. Focus on high contrast and rich, vivid colors. Ensure the final look feels like a physical masterpiece found in a modern art gallery.
