Certainly I've been using proper cycling shorts and attire longer, but I too was a little leery of them and purposely did not want to look like all the rest as that felt like capitulation! However it is one of those things that once you do, then you wonder why you waited so long. My journey from bike shorts to bibs was a little of the same thing, though personally I'm fine with either. I don't have the fit issues some others seem to allude too.
Probably one of the biggest thing I had to laugh at myself for was using friction shifters on the downtube so long thinking nothing could be better. Then about 2107 I put 105 5800 on a '91 Paramount frame and those days were over and new ones beginning.... steel to carbon, rim brake to disc brake, cable pulled to electronic shifting, cable pulled to hydraulic brakes.... boy I've laughed at myself a lot for my mistaken beliefs! <grin>
