The comparative form of blouse, meaning more disheveled, untidy, or loose in appearance than something else.
From blouse (or blowsy in dialect), with the comparative suffix -er added. Blouse in this sense comes from Dutch blouse or German Bluse, originally referring to loose peasant garments.
The word 'blousier' shows how the same root word can have multiple meanings—one is a specific garment, but 'blouse' in dialect means 'untidy or slovenly,' which gives us this more critical comparative form.
