Maybe it’s the city’s roots as an industrial and agricultural powerhouse, or perhaps it’s simply the laid-back Midwestern attitude that permeates the majority of interactions within the city. Whatever the reason, Kansas City  is hardly a formal metropolis, so feel free to pack casual attire for your trip.
However, as in most cities, a few exceptions exist to the casual dress code. If you plan to thoroughly explore Kansas City’s nightlife , especially at places in the Power and Light District and lounges like Blonde , “dress to impress” codes are strictly enforced. For these your best bet, male or female, is to bring dressy pants and shoes along with an equally dressy top or button-down. Ties, jackets, and gowns are worn at only the most formal of occasions.
You may also want to do a quick bit of research regarding the restaurants in which you plan to dine. The overwhelming majority of Kansas City restaurants  welcome diners in casual attire, but there are a few fine-dining establishments that prefer to see guests arrive in dressier — yet still not formal — clothing.
If you’re traveling to Kansas City for business, you’ll want to bring a few suits and business-casual outfits. Kansas City professionals, both local and out-of-towners, are often in suits or something equally as dressy at bars and restaurants throughout downtown and the Plaza for lunch and dinner meetings.
Also be sure to pack a light rain jacket or an umbrella. Kansas City  weather is as unpredictable as it comes, and what starts as a brilliantly sunny day could end in rain showers — or vice versa. In fact, I’ve seen it rain when there’s not a cloud in the sky, a phenomenon I haven’t quite been able to explain.
If you’re traveling during the spring or fall, you may also consider a heavier sweater or jacket to slip on during the cooler evening hours, especially if you plan on spending a lot of time outside. If you’re traveling during winter, make sure to bring several layers. Consider long johns or similar undergarments layered under a long-sleeved T-shirt and sweater.
If you’ll be in and out of buildings, opt for fewer layers and instead stay warm with a heavy coat, scarf, gloves, and a hat. If you expect snow while you’re in town, a pair of boots makes walking more comfortable.
