What is the latest trend in formals in Pakistan?

I’ve got a few weddings to attend this year, but have no clue what the latest trends are for formals, can you please advise?

What are the latest styles?
Fabrics?
Hem lines?
Embroidery?
Colour combos?
Trousers? shalwars? Churidaar? Etc

Thanks

The shirts are like gowns very long, you can't see the pants underneath.
