Movie stars look glamorous when they walk down the red carpet in their designer gowns. Glamorous means full of glamour, beauty, and excitement.
Glamorous comes from the Scottish gramarye meaning "magic, enchantment, spell." See a glamorous woman walking down the street and you might be captivated or enchanted by her beauty. A person can appear or act glamorous. An event like a really over-the-top party can be glamorous. Or a lifestyle that one chooses for herself can be glamorous, full of parties and swanky events.
