  We compute the resistivity anisotropy in the nematic phase of FeSe from the
static solution of the multiorbital Boltzmann equation. By introducing disorder
at the level of the microscopic multiorbital model we show that even elastic
scattering by localized impurities may lead to non-trivial anisotropic
renormalization of the electronic velocities, challenging the usual
understanding of transport based only on cold- and hot-spots effects. Our model
takes into account both the $xz/yz$ and the recently proposed $xy$ nematic
ordering. We show that the latter one has a crucial role in order to reproduce
the experimentally-measured anisotropy, providing a direct fingerprint of the
different nematic scenarios on the bulk transport property of FeSe.
