Fair point.
My 9th grade math teacher probably didn't smell of vodka at 8 a.m. before he graduated...
...actually I'm sure he did ^^. (my sarcasm detector might not be working here, not sure)
To expand: There are 3 stages in your science career:
#1 you are unimportant, and everyone knows that
#2 you would like to be important, and everyone needs to know that
#3 you are important, and everyone knows that
In #1 and #3 you can dress as you want, nobody gives a rat's rear end.
In #2, you need to dress up at the right occasions.
