What you wear at work may also be dependent on the facilities available at work. If your rides to work are fast, long, or part of your training, then it's pretty damned likely that cycling kit will function the best. A bonus to having the cold weather cycling kit, and another nail in the coffin of insipid "gimmick" claims, is that cycling kit can of course be used for riding places other than work, like long rides or fast rides on the weekend. On faster rides or rides where there's significant exertion, cycling clothing will manage moisture better than street clothes. If your workplace is configured such that it's not possible or is difficult to change between cycling kit and work clothes....well....you may not have option of even considering cycling clothes.
If you describe your ride to work more--length and how you plan to ride (casually, hard, and etc)--as well us what the rest of your cycling is like, people might be able to make better suggestions.
