Something gussied up has been made more attractive, but in a showy or gimmicky way, so it’s often not intended to be a compliment. It can also refer to dressing in one’s finery for some special occasion, when it is intended to be taken more straightforwardly. It is usually considered to be an American expression, dating from the late 1930s or thereabouts.
"I have a hot date tonight, time take a shower and get myself all gussied up."
