Many of my clients work in the business arena where a strong physical presence is a definite advantage. The shorter woman's image becomes diminished when she wears overpowering clothes. Wear one continuous color from shoulder to hem. This lengthens the silhouette. If you break that vertical block of color with a wide belt, for instance, the eye stops short, making you appear shorter and wider.
Accessories can be overwhelming on the petite frame.
However, an appropriate size scarf or earrings will draw the eye up, focusing attention on the face. Keep Prints in proportion to your figure. In general, prints should be no larger than your hand. The trick is to achieve the proper fit and proportion and to maximize appearance by paying attention to the elements of line and balance in all outfits. My clients tell me that once they understand this, they feel more confident and self-assured.
