Bell sleeve blouse
Office look does´t necessarily have to mean blazer costume anymore since there are plenty different kind of offices nowadays, like creative work spaces or informal offices where a business suit is not required.
The bell sleeve is a nice micro trend this year and allows you to wear a different shaped blouse. For a formal office look make sure to not show any belly while wearing a cropped blouse. Therefor a high waisted pencil skirt or cigarette pants are highly recommended. This look suits skinny and curvy ladies very well.
It´s all personal.
