I just don't think this tote style was designed to be that small. It looks like a dollhouse model to me. But that just means if one comes out, there will be more for those who love it
I do think it would do better and work better if it has a strap and maybe is simplified - like the nano Sac de Jour. The SdJ is basically a Birkin without a flap or a turnlock, and the nano size looks pretty good to me as mini bags go (it's also 22cm not 20).
So maybe not a Birkin 20, but a version of the Birkin that works in mini size.
I just hope H doesn't take mini bags to Jacquemus level. I love him as a designer but he means those bags satirically, and that's not H, to me.
