Men looking at men wearing stylish clothes: not haram
Women looking at women wearing stylish clothes: not haram
Men looking at women wearing stylish cloths or viceversa: haram (shouldnt happen in islamic fashion shows)
Issue of photography is disputed among scholars
Videography from what i know is halal by ijma'
Media, not haram.
catwalks ... depends on the person. if it sexually arouses him then he cant look at men doing that let alone women.
Music, i will go with you and say its haram therefore it shouldnt play. But doesnt mean that fashion shows can exist without music.
The majority of fashion shows in the west actually show case women showing less skin than people in the streets ... so imagine how little skin will be shown in islamic fashion shows?
Besides if its haram to attend fashion shows because of showing off skin and what not, then imagine how haram it is to walk the streets in the west? Where people sometime actually walk b*tt N*k*d in the streets.
Go on google and search images of islamic fashion shows and just see how most of the models cover all of their body (with the exception of face and hands). Look at the audience were most of the imagine u would find will have female only audiences.
So in a sense, you can make fashion shows islamic if you really have the imagination and the will power to turn something that is haram into a halal thing without breaking any of the rulings of islam.
If the fashion show ur link talks about is unislam then sure it should be there at all. but if it is islamic then ... Still not the best place to do it but if there is nothing haram about it then id let it pass but wouldnt recommend it. And Allah knows best.
