(WAFF) - Look smart - being resplendent in a sharp outfit - while sounding smart by using the word "resplendent!"
When you're looking resplendent, you are dazzling; you are radiant. As Billy Crystal might say, "You look marvelous."
In this example from Dictionary.com, sparkling appearance can take a literal context:
"The tall hill forest, resplendent in the aftermath of rain, was aglow in emerald light."
You can see the root of the word "splendor" in this word; both words are stunning examples of how to describe a person or a location's natural beauty.
