I probably would never say anything constructive to you about it, I'd just ridicule you behind your back, which would impact your career and you would'nt know abou tit. so we are helping you out here, and you are getting all pissy about it.
so, you want good advice? get yourself some simple well made off the rack stuff from BB or Jos bank or something similar. button down collars, standard cuffs. blue shirts, gray or khaki pants. maybe good, simple shoes. get a nice timex beater. lose the jewlery. there you go, bob's your uncle.
This is absolutely correct. It's all about messaging and projecting an image that matches people's preconceptions. If there isn't a match people are uncomfortable and that leads to doubts and hostility. At this point in your career you want to be seen as low maintenance and approachable so dress exactly as globetrotter describes. In my work I use clothes a lot to elicit particular responses from people depending on what I need from them and how I need them to act - there is a dog whistle effect with clothes that most people never see.
