Now there are thousends of reverts (like me), as muslims as any arab or indo-pak, and that are our dress... not the thoub, not the shalwar, not the lungi, and the western dress has became the dress of many cultures around the worls, losing it´s "western-only" trait. I do not see people complaining about the shalwar kamiz, that is in fact hindu in origin, but only see people compining about suits and jeans, no matter if thet are loose, baggy and above the ankles... why this? It is not like they are wearing a chatolic priest robe, or a jewish kippa and talit.

This is NOT true. The shalwar kamiz is a Muslim introduction to India, and not a traditional hindu dress.
And do you know what the origin of European formal wear is (suit, tie, jacket)? Not a priest robe, indeed....

I know of pious muslims reverts who pray correctly, wear a beard (even if it is prohibited in their workplace), even cover their heads with a skullcap in prayer, but do not like to dress daily in thobe/shalwar kamez because they feel like they are wearing a costume... it is just not "their" clothing. Similarly, I know pious muslim reverts who do all that, and wear shalwar kameez to work in their offices every day out of love for the sunnah of the Prophet and a wish to be identified as Muslims rather than blending into the crowd. Sometimes, Islam means pushing yourself to do things that feel uncomfortable in the beginning. if you make effort, Allah will not only make it easy, but you will start to have advantages in this world from loving the sunnah.
I have heard from many friends that received advancements and won jobs after wearing Muslim clothes to interviews/evaluations. Most people will respect someone that is not afraid to show what they believe in openly, and standing out from the crowd also has its advantages.
