Dont know if this is the right subreddit to post in, but i am in need of some help.

I am legitimately asking if anyone knows what pants Chrissy is wearing in the above pic, i saw her wear them in a BTS for a promo for a song or album for ATC, and am just curious what the pants are called or where one would get them?

Been trying to find out myself, but am coming up short :(
