It depends how thoughtful you want to be about your style though ?
If you do consider that your style is your public API and a mean of personal expression, it needs a good amount of trial and error. The first english speaking place that comes to mind for this is the subreddit malefashionadvice .
There are also companies (that actually target engineers because it is a very engineery thing to do) that will sell you a "uniform" made of 3 times the same chino, 3 times the same hoodie (maybe some color variation), some simple tshirts and undergarment and done.
