luxury good may become a necessity good or even an inferior good at different income levels. Some luxury products have been claimed to be examples of Veblen goods, with a positive price elasticity of demand: for example, making a perfume more expensive can increase its perceived value as a luxury good to such an extent that sales can go up, rather than down. However, Veblen goods are not synonymous with luxury goods. Although the technical term luxury good is independent of the goods' quality, they are generally considered to be goods at the highest end of the market in terms of quality and price. Many markets have a luxury segment including, for example, luxury versions of automobiles, yachts, wine, bottled water, coffee, tea, foods, watches, clothes, jewelry, and high fidelity sound equipment.

Some financial services, especially in some brokerage houses, can be considered luxury services by default because persons in lower-income brackets generally do not use them. Luxury goods often have special luxury packaging to differentiate the products from mainstream competitors.

Luxury goods have been transformed by a shift from custom-made (bespoke) works with exclusive distribution practices by specialized, quality-minded family-run and small businesses to a mass production of specialty branded goods by profit-focused large corporations and marketers. The trend in modern luxury is simply a product or service that is marketed, packaged, and sold by global corporations that are focused "on growth, visibility, brand awareness, advertising, and, above all, profits." Increasingly, luxury logos are now available to all consumers at a premium price across the world including online. Global consumer companies, such as Procter & Gamble, are also attracted to the industry, due to the difficulty of making a profit in the mass consumer goods market. The customer base for various luxury goods continue to be more culturally diversified, and this presents more unseen challenges and new opportunities to companies in this industry. The three dominant trends in the global luxury goods market include: Globalization: Consumers in some countries are becoming wealthier, thus new markets are opening for luxury marketers.
