Shop your Triangle Shape. Women's choices for Plus and Missy triangle clothing. The triangle shape generally has narrow shoulders. The bust measurement is smaller than the waist measurement, and the waist measurement is smaller than the hip measurement. Generally speaking with this figure, the key is balance. Opening up the neckline draws the eye upward, elongating the body. Wearing things with an empire waist is another great way to lengthen and balance a triangle. A wrap top tied under the bust achieves the same look. Drapey garments should graze the figure of this woman instead of standing away from the body. When clothing doesn't touch the shape, you can end up missing all of the great features of this figure.
