  Monopole operators play a central role in 3 dimensional supersymmetric
dualities: a careful understanding of their spectrum is necessary to match
chiral operators on either sides of a conjectured duality. In Chern-Simons
theories ($k\neq0$), monopole operators acquire an electric charge, thus they
need to be "dressed" by chiral matter superfields to be made gauge-invariant.
Here we present strong evidence that "dressed" monopoles appear in $SU(N)$
chiral theories even for $k=0$ because of mixed CS terms generated along
certain Coulomb branch directions. Our analysis is based on the dimensional
reduction of 4-dimensional dualities which, for the simplest s-confining case,
allows us to easily identify the spectrum of the electric chiral operators.
