Luxury is a sensory experience. The smell of fresh linen and expensive cologne. The tactile sensation of cashmere throws and cool marble floors. The sight of city lights reflecting off a champagne glass. Skilled authors use these details to lower the reader’s (and the character’s) inhibitions. When a character is wrapped in a hotel robe that costs more than their monthly rent, they act differently. They feel invincible, reckless, and open.
