We evaluate the model-dependent piece of $O(\alpha)$ long-distance radiative corrections to $\tau^- \to \pi^- \pi^0\nu_{\tau}$ decays by using a meson dominance model. We find that these corrections to the di-pion invariant mass spectrum are smaller than in previous calculations based on chiral perturbation theory. The corresponding correction to the photon inclusive rate is tiny (-0.15%) but it can be of relevance when new measurements reach better precision
