Do Muslim men have to wear specific clothes?

Answer 1

no,

It is not required for Muslim men to wear special clothes. Per Islam religion, It is required only for Muslim clothing to meet Islamic guides irrelevant to which styles they wear to suit their specific country and community cultures and traditions.

refer to question below for what a Muslim men should wear.

Answer 2

Muslims have to cover their private area, especially when they go to pray.

The minimum private area for a Muslim men is (vertically) from knees to navel.

For Muslim females, the minimum private area is everything except hands, face and what is neccessary to be open.

As long as the minimum is covered, the muslim may pray.

It is also customary to not wear clothes with too fancy artwork on and not to wear clothes that could distract other people who wants to pray also. For this muslims today wear robe-like clothes that would make it easy to perform the praying act.

Covering more than the minimum body area is not a sin, and is a choice of the individual.
