Being beautiful is not enough. If a man notices that his girlfriend doesn’t take proper care of herself, it may put him off. Even slobs want their women to look neat and smell nice. Men are so fine-tuned when it comes to a woman’s hygiene that to them a well-cared woman often appears more beautiful than a stunner who looks filthy and untidy. Sloppy clothes, dishevelled hair, dirt under fingernails… Lay off it, unless you mean to push him away.
