Emily Cooper (Lily Collins) will be exploring Rome in Emily in Paris Season 4.

A new trailer shows Emily enjoying her Roman adventure ahead of Part 2's release on Sept. 12.

The season includes an Audrey Hepburn tribute, with Emily channeling Hepburn's style.

Emily wears a Charade-inspired ski outfit during a trip to the Alps in Part 2.

Creator Darren Star sees a connection between Lily Collins and Audrey Hepburn.

Star believes that the show captures the "Old Hollywood" feel like Hepburn's movies.

This season introduces winter in Paris, adding a fresh element to the show.

Executive producer Andrew Fleming highlights the new "textural feel" of Paris in winter.

Paris in winter is depicted as just as beautiful, if not more so, than in summer.

Emily's style evolves, becoming stronger and reinterpreting Parisian fashion.

Costume designer Marylin Fitoussi mentions that they took maximum fashion risks.

Emily's growth is evident as she asserts herself more confidently this season.

Part 2 will feature Emily's Roman holiday in Italy.

Will Emily end up with Alfie or Gabriel? Only time will tell

The Roman holiday was announced by Lily Collins at a special fan event last year.
