The most important points in the Hadith of Rasullullah May Allah's peace and blessings be upon him regarding dressing are:
1) The clothes should conceal the body adequately.
2) They should impart dignity and good looks.
3) They should not fail to satisfy the requirements of adequate concealment of the body.
4) Nor should they be so ugly and clumsy that instead of enhancing beauty, they mar the wearer's appearance.
