  We present various confinement phases of three-dimensional $\mathcal{N}=2$
$Spin(N)$ gauge theories with vector and spinor matters. The quantum Coulomb
branch of the moduli space of vacua is drastically changed when the rank of the
gauge group and the matter contents are changed. In many examples, the Coulomb
branch is one- or two-dimensional but its interpretation varies. In some
examples, the Coulomb branch becomes three-dimensional and we need to introduce
a "dressed" Coulomb branch operator.
