v. Slang 1. To dress someone in fancy or ostentatious clothes, especially for a special occasion: The parents dolled up their child in sailor outfits. The costume designer dolled me up in 19th-century clothing. I got all dolled up for the big Halloween party.
2. To add embellishing details to something in order to make it more attractive: I dolled up the boring lecture by adding a lot of jokes. There wasn't much content in the manuscript, so the author had tried to doll it up with interesting stories.
