I believe how you project yourself to others and how they perceive you is primarily judged in short term by the clothes you wear.

Every one will agree that a well dressed person, with combed hair, looking clean and smelling good will definitely attract more people than others. Yes, a cheerfulness in demeanour will add to the seasoning.

It naturally attracts respect. It creates a sense of class and power.
You will yourself feel a positive vibe!

And this sums it up!

In the long run only ones character and quality of work pays, but for day to day engagements... looking good matters.
        It does not mean being obsessive about clothing and accessories. But just wear clean clothes, well ironed and that looks good on you. Also, be mindful about the occasion. Feel free to be funky in parties or informal gatherings but do have a gentleman's look in formal gatherings or if doubtful on what to wear.

The great South Indian saint-philosopher-reformer Shri Narayana Guru said that his main intention behind installing new temples was that people would take a bath and wear clean clothes for the sake of entering the temples. He said that one of the reasons behind untouchability still prevailing then and the widespread diseases was lack of cleanliness. Which was true to a great extent. He said that if people were clean, healthy and wore clean clothes then no one would dare to shoo away the so called 'untouchables' or disrespect them.
    He Succeeded !!

            PS: I have always seen that highly successful, well respected people whom I adore and who inspires me well dressed, looking good..... Have you seen otherwise ?!
