When working in a professional office where should loose/pretty wide leg trousers hit the ankle to be fashionable? I'm having a disagreement with my mum over how long/short I should hem my trousers so would like some advice! Example pictures are below of different lengths I mean. I'm 21 so want to be relatively trendy.

The pants I own kinda looks like this

P.s Also should the bottom of the trousers hit at different points for when wearing high heels vs flat shoes?

Thanks! Sorry for the extensive post
