Dress & Attire

Q: Is it better to wear one's watch on the left hand or on the right hand?

Q: Are men allowed to have embroidery on their clothes? Even little bit embroidery around the neck of the kurta/shirts. I understand heavy and lot of embroidery is a women thing and must be avoided but nowadays we find kurtas/and shirts with little bit work around neck, should it be worn by men or should the garments of the men be plain?

Secondly, it is in a Hadith not to copy non-Muslims. Nowadays Muslim men wear pants and shirts which I think is a western originated dress. You are treated as a weird person if you don't wear, so what should be the ruling about it?

Thirdly, I read somewhere that men should also not wear tight clothes, is it true? Then pants are fitted garments?

Fourthly I also read that men should also not dress up in a way that attracts the opposite sex. 

Please guide me how much of the above information is correct or not. And what should be the ruling about the other questions I asked?

Q: Is the wearing of a ring all the time a sunnah since we wear it as jewellery (as adornment)?
