Shalwar, Qamees and a Cap
NO! Whoever wrote that muslim imams wear shalwar, qamees and a cap are completely wrong, and clearly pakistani! ;/
There is no general dress code for what an imam can wear because muslims live all over the world and according to there culture they can wear whatever they like aslong as they cover all the body parts which all muslims have been told to cover.
Hope it helped 😀
