Dress code for Men in Islam

Islam does not only ask women to dress modestly, it also urges men to dress modestly.

What is awrah?
Awrah (Arabic: عورة‎) is a term used within Islam which denotes the intimate parts of the body, for both men and women, which must be covered with clothing. 

For the man, the 'awrah is defined as the area between the
navel and the knees.

Within the definition of 'awrah for men and women, all
the four basic requirements are
essentially the same:

1. Man should fully cover his 'awrah.

2. Men's clothes should be loose enough so as not
to describe what he is covering (his 'awrah).

3. They should be thick enough so as not to
describe the color of the skin or the parts
required to be covered.

4. They should not be designed in a way to attract
attention. The basic rule of modesty and
avoiding "show off" applies to all believers’
men and women.

The three other additional requirements discussed under
the Muslim woman's code of dress apply to men's
clothes as well:

1. They should not be similar to what is known as
the female dress.

2. They should not be similar to what could be
identified as the dress of unbelievers. (Just to maintain their own identity)

3. They should not be clothes of fame, pride, and
vanity.
