Studies of thrust distributions and jet shapes in $e^+ e^-$ collisions using $730 ~pb^{-1}$ of data collected between 91 and 209 GeV with the ALEPH detector at LEP are presented. The event and jet shapes are studied for the first time with both tracker and the calorimeters in bins of the event charged particle multiplicity or event activity in order to reveal the possible modification of those observables in the high particle density environment. The results from the archived ALEPH data are compared to predictions from various event generators which were tuned to describe the inclusive event shape data at LEP, as well as theoretical calculations.
