A thickened aqueous fabric softener composition comprising at least one surfactant and a polymeric rheology modifier, wherein said polymeric rheology modifier is the polymerization product of (i) an alkyl ester of acrylic acid or methacrylic acid; (ii) a monomer selected from the group consisting of a vinyl-substituted heterocyclic compound containing at least one nitrogen or sulfur atom, (meth)acrylamide, a mono- or di-alkylamino alkyl(meth)acrylate, and a mono or di-alkylamino alkyl(meth)acrylamide; and (iii) an associative monomer. The polymeric rheology modifier does not require a make down step to slurry or disperse it into a fabric softener composition. The thickened fabric softener compositions do not affect rewettability, nor do they build up on cloth in multi-cycle washing. In addition, the thickened fabric softener compositions provide softening and reduce the formation of wrinkles.
