Even at this point... the only doll that comes close to Arlequin's design is Olimpia.
The simplicity of its design hides a beautiful complexity, missing an arm and using an arm as a spear, and having a hidden blade in its main arm at the same time, like layers.
Olimpia has more going design-wise at first glance, and even in the hidden details, but everyone feels cohesive and equally adds to the charm.
