Styling a closet niche vanity requires fitting a thrifted or DIY-painted vanity into a cozy recess. Use a soft warm neutral color on the vanity to coordinate with room walls. Layer lighting with a rescued lamp or wall sconce to brighten the space. Add a vintage mirror and minimal shelf styling for organization. Keep the niche clutter-free with essential items only. This setup maximizes small spaces, creates an intimate dressing area, and ties into the eclectic vintage bedroom look effortlessly.
