A somewhat antiquated
expression that means you're dressing in a flashy, ostentatious
style. You're out to impress people with your slick clothes.
"Bill, putting on the dog tonight, huh? What lovely lady
are your taking out?"
The expression, which comes to use from the 19th century, has its origin in the custom of rich people owning lapdog
s, like Maltese dog
s. Lapdogs were popular in Ancient Greece and China
. During Queen Victoria
's reign, she was given some lapdogs as gifts and they became an instant rage
So basically, no one going out the door and dressed for society was complete without a tiara
, a cape, and a highly pampered pooch
on the end of a leash
