You two are posing as a couple as part of the disguise.
Your new names are David Garrett and Cheryl Garrett.
When you say "casual clothes" there can be different kinds of casual disguises. A hobo would look out of place in a good neighbourhood. A well dressed clean-shaven young man would be out of place in a sleazy neighbourhood. An elderly man (wigs and facial props) with a bag of groceries can fit in anywhere.
Change of shoes is also important in this business. Clean tennis shoes is a textbook tradition, and any other shoes for traveling. You don't want foreign soil on your work shoes to pin you as coming from a certain place. And the tennis shoes are usually disposed of immediately after the job.
By default, we're going yuppie-casual. Your targets initially shocked the world when their sub-urban yuppie backgrounds were revealed.
