Spiff 

Adjective, describes a person who dresses and look spiffy all the time for no reason, usually dresses in a suit and tie or other nice outfit with a tie like jeans/shirt/vest/tie or khakis/shirt/tie

Matt began to realize his level of spiff when he began to wear a suit and tie every day for no reason. If he wasn't in a suit and tie, he was wearing khakis or really nice jeans and a shirt and tie. Pure spiff.
