I think it's absolutely meaningless, like the majority of menswear collections I am seeing... It's without doubt wearable and partially commercial, but lacks an edge and identity... It would be OK for a decidedly non-design/back-to-the-basics brand like A.P.C. where you are looking for everday staples at a decent pricepoint, but for a label like Marni, it simply isn't enough - most of these pieces could be everything, if you cut out the label tag.
Somebody said it's too utilitarian, but I don't see anything overtly detailed in the clothing that would suggest an overtly functional background.
It really all looks like an unloved stepchild of the marni womenswear, if you ask me.
