I like both fits, but if I had to nitpick here's what I'd say:
Istasi – I bet that jacket feels incredible, but I've never really dug the floppy collar. When zipped up like that, it sort of looks like a club collar that's resting at the wrong angle.
Lesamourai – The individual pieces are great, but I wasn't digging the choice of white footwear + white bd. But maybe the sneakers aren't as bright in real life? In any case, I think either a different shirt up top or throwing on boots would make it all a bit more interesting.
