I think it looks fine.
The stripe/colorway is derived from suiting, but the the rumpled, unconstructed coat is much more casual than any business suit & works well with worn denim. These stripes can be woven & tailored to span a wide range of formalities today; not so 10 or 20 years ago.
I see the jeans were rolled up to different lengths. Were you cycling?
Nope... I just didnt roll them right
