Might be a contrary opinion, but I feel like the Row rips off other designers too. The Margaux makes me think of the Hermes Bolide for example (handles and shape), and I’m sure I’ve thought similar of other designs of theirs in the past. I do see what you mean about the buckle detailing on this though, that’s maybe a bit close for comfort!
I think bag trends happen in the same way as clothing, we’re all ‘inspired’ by each other and the more popular a shape is then more designers will make similar so that they’re in on the game. Everything is now getting bigger and either more professional or slouchy, which kind of suits this aesthetic.
It’s true The Row is way smaller but I reckon they actually choose to not spend loads on marketing and have it as a ‘If you know, you know’ brand, as the Olsen twins could realistically plough more money into marketing if they so chose.
