Clothes again

After the stint at the college, I went to an IIT. There were boys who wore what I think were the same pair of jeans for 4 years out of the 5 they spent there  (those days it was 5yrs for BTech). The day they joined, they stopped shaving (where's the time if you get up at 7 45 for the 8 am class).  So someone would say "This is  Vikram" and a bearded face would nod and say "Hello" ...or "This is Alok" and a slightly, imperceptibly different bearded face would nod. Both wore identical jeans of indeterminate color which was allegedly blue when it was in the shop.
Come  placement time.....no beards, no dirty jeans. Bright young men with clean shaven faces, wearing nice shirts and well tailored trousers..........one would need to be re-introduced to figure out which of them was Vikram and which was Alok.
