Abstract
In this review article, we revisit the connection between dressing of scattering states in quantum electrodynamics by clouds of soft photons, and their dressing by (generalised) Wilson line operators. In particular, we show that the leading and subleading soft conformal dressings considered in the context of celestial holography can be straightforwardly obtained from generalised Wilson lines, and that this only requires knowledge of the asymptotic behaviour of the photon field near null and timelike infinity.
