"With the idea that instead of shopping all around New York, the attendees could have the city's best shops brought to them, retail outlets were set up with unique offerings of fashions, home decor, toys and cookware."
Even more than the two unnecessary passives that follow, it's the introductory phrase that floors me: "With the idea that instead of ..."
There was no coming back from that. I overhauled the whole sentence, making it something like:
"New York's top retailers set up boutiques at the festival, creating a one-stop shop for some of the city's finest fashions, home decor, toys and cookware."
Amazing how that tangible subject + verb formula can save a bad sentence.
