Could you tell me the difference between the two sentences below giving some advice ?
1. You should pay more attention to your appearance.
2. You should have paid more attention to your appearance.
I know both advice-giving sentences above are correct, but I wonder what the difference is in advice-giving sense.
I am much obliged to you for your help.(newly-learned)

However, when I give some advice, they are definitely for the present or future because I want you to be good in the present or future, not the past. So, why do I still have to say:
You should have paid attention to your appearance.
(refer to the past)
