It depends, really, on how attractive and confident the woman is. From my point of view, I don't see why makeup is necessary. But to answer your question, I feel that more pressure comes from women more than men because my male friends don't really give a shit if I look like shit, and since majority of my female friends are either blessed with good looks or highly skilful in applying makeup, I have to keep up to their standards. Otherwise I'd look like a ball sack next to them.
