Stress makes people look better. Keep an eye on some people whose due date for an important duty is coming. The closer it gets, the better he/she looks. For instance, Phd qualification exams, thesis presentation, final exams etc. The fact behind it is the act of escaping from responsibilities. They focus on the things other than the fundamental job. They find new things about themselves, hobbies, interests or more basically they improve their appearances. But it does not goes like this till the end, when a few days remain, they start to look messy.
Or they realised that and share on their blogs :)
As shown in the graph, you start to take care of your outlook, hair, apparel etc. and then your attractiveness and beauty start to raise, but at the end, it all goes away by the higher power: more stress.
