My wardrobe style has changed quite a bit since I moved to Seattle. All my corporate dresses and jackets are now at the bottom of my suitcase. Most of my high hills are still at the storage as I don't attempt to wear them walking up and down the hills in Seattle.
This is really what I wear to work these days. It's practical for the Seattle raining weather. I can quickly put myself together in the morning, go to the gym and head to the office.
You need a good water proof jacket to handle the daily rain. Everlane Anorak has been my daily choice for the season. Athleta highline hybrid cargo tight is the best pair of leggings I owned. It's well constructed to keep me warm and the material is thick enough so I don't need to worry about the panty lines showing. I am ordering another pair as we speak!
As for the shoes, Nike has been my new favorite commuting shoes these days. They are so lightweight and provide enough support for my feet.
