We study dressed inflation with a cuscuton and find a novel exact power-law
solution. It is well known that the conventional power-law inflation is
inconsistent with the Planck data. In contrast to this standard lore, we find
that power-law inflation with a cuscuton can be reconciled with the Planck
data. Moreover, we argue that the cuscuton generally ameliorates inflation
models so that predictions are consistent with observations.
