Heres when and why. Professors are stuffy. You must be a well dressed man with style and taste. The color of preference for a diamond-cutting erection or a phallic symbol is red. There are 200 years of subconscious learning helping you gain this edge by announcing on a subconscious level that you are a virile, powerful Man, not a boy.
Boys arent dressed like that.
Young women who will date you are tired of boys. They want a Man. Look like a Man and you have begun the seduction. All attire is decoration and manipulation. Yes, it is indeed exactly that, an exceedingly small chance.
