Although, Wes works with such talented and recognizable costume designers as Karen Patch and Milena Canonero, Anderson always checks every little detail by himself. He really loves uniform, headgear, vintage clothes, glasses and mustache. That's why we see a lot of characters wearing them.
And, of course, we didn't mention the main peculiarities of Wes films which are symmetry and centring. Anderson is crazy about it. In his films we always see geometry, angles, smooth lines. He is a real perfectionist.
Thus, Wes Anderson created his own unique style and became one of the most recognizable directors of modernity. We can name hardly any filmmaker being as authentic in visual way as Anderson.
That's why we really recommend you to watch films from our list:
Academy Rushmore (1998)
Fantastic Mr. Fox (2009)
Moonrise Kingdom (2012)
Isle of Dogs (2018)
The Grand Budapest Hotel (2014)
