One thing is for certain, the entire fit makes zero sense. That caban / flares / Lukas combo is tragic.
I think on a different build and perhaps black denim would be fine. I don't think the combo itself it problematic.
I didn't exactly clue into what you meant until I really thought about it. Hedi never showed brown suede boots for men on his runway looks at Celine at all so far. Whereas he featured brown suede boots for men in fw13, ss15, and fw16. I could see the Lukas being replaced by Berlins, Camargues, or white Jacno 40s from ss20.
So, unless Hedi shows it together, it's wrong?
