Is it acceptable to wear the same outfit every day? I am a male graduate student in natural sciences at a public university. I want to simplify my life a little bit by wearing the same outfit (more or less) every day. (Obviously I would have multiple copies to be hygienic.) I tend to wear untucked casual button-downs with some casual khaki pants and sneakers. Would this be looked down upon by the faculty? I am not so worried about other graduate students, but I do not want to make a poor impression on the faculty. Any guidance on this would be much appreciated! 

Of potential importance: I am TAing one class right now and will be taking two classes this upcoming semester.
One of my faculty colleagues who just received tenure (at my r1 university) has worn basically the same outfit (same colored button-down shirt with khaki trousers) for the past decade - from graduate school to his current position (he may have indeed been wearing this his entire life, but we only have data for the past decade). I believe his closet only has one type of shirt and trousers. 

Aside from gentle ribs from others about his 'uniform', it's well tolerated by others as it's a minor eccentricity compared to some of the other faculty.  Just be open to someone asking you if you: 1) have multiple shirts or a single shirt; 2) wash them regularly.

tldr: If it saves you money / brain-cycles  / spoons / closet-space to wear the same uniform clothing every day, do it. It worked for Steve Jobs, it can work for you.



Fine print: There may be a gender factor as men in academia and industry who basically wear a uniform are well known but it is rare to encounter women who do the same. This requires more exploration.
