Abstract: We show that the `dressing- approach, which describes physical charges asgauge invariant composites of matter and clouds of gauge bosons, arisesnaturally in gauge theories. We give perturbative examples of dressings forboth asymptotic charges and for states in which the fields are confined to acompact volume as is required, for example, by causality in pair creation. InQCD, we use dressed states to demonstrate explicitly how Gribov copies obstructthe non-perturbative construction of colour charges.
