I've been running Aikido classes in street clothes for several years now. Not all the time, but regularly. And I've been adapting the longer, sweeping classical forms of Aikido to more common and contemporary types of attacks. Some people like it. Some people don't. Depends on what the person's goals in training are. Responses to the clips I've posted on YouTube have been generally favorable, though there are always the idiots who just want to make assinine comments. My ukes don't fling themselves around and make my technique look beautiful, so I'm not usually accused of overly collusive performance of technique. Regardless, there are always people who want you to know they think you suck. Ah, well. You can please some of the people some of the time, but you can't please all of the people all of the time. That's okay with me.
