When youre dressing for the day, first select the suit or jacket dress that youre going to wear. If youre wearing a jacket dress, youll only have two major pieces of clothing, but if youre wearing a suit for the day, select a shell or blouse to wear with it. Petites especially may want to think twice before wearing a blouse that's ruffled because the ruffles may be perceived as too girlish at work.
Even if you think that youll be keeping the suit jacket buttoned up all day, at least wear a shell. When you raise your arms, the bottom of your jacket may also raise above your waist, and if youre not wearing anything under the jacket, your bare midriff will show.
