It's a super heavy and comfortable pant. suitable for all formal and elegant looks.

All in good condition, it's getting tight to me and length is also bit short for me. (my height is 5.3)

2 waist button
Zip
knot (from inside to secure)
Astar (It's a heavy pant with very soft material from inside, there are 2 layers)

PS: not so sure about the exact fabric name.
