The term "dressier" refers to something that is more formal, elegant or sophisticated in appearance. A dressier look typically involves wearing clothing items that are tailored and refined, with a focus on quality materials, classic styles and polished details. This could include things like suits, blazers, blouses, skirts, dresses, heels or other upscale accessories. The idea is to create an overall look that is more formal and put-together, suitable for special occasions or professional settings where a smart and polished appearance is desired.
