Someone or something that is resplendent has great beauty and is a pleasure to behold. "She was there, at the base of the stairs, resplendent in her flowing gown and jewels."
When people or things are resplendent, they are dazzling, splendiferous, glorious, or lovely. The adjective resplendent comes from a Latin word that means “to shine brightly.” The gilded entranceway was resplendent in the golden glow of the afternoon light. When he flashed his resplendent smile, she was helpless against his charms.
