For instance, using "stunning" gives a strong admiration towards someone's beauty. "Radiant" is great for describing someone's glowing and positive aura. "Impeccable" connotes that someone's appearance is well-groomed and flawless. "Gorgeous" is a common word to describe someone's beauty and attractiveness. "Splendid" implies that someone's appearance and style is impressive and grand. "Dapper" is a great term for describing a man's neat and stylish appearance. Using these synonyms for "looking good" can add enthusiasm and flair to your compliments.
