Shop your Triangle Shape. Women's choices for Plus and Missy triangle clothing. The triangle shape generally has narrow shoulders. The measurements on this shape gradually increase as they go down the body. The bust is the smallest measurement, followed by the waist, and then the hips are the widest measurement. Generally speaking with this figure, the key is to balance the top and bottom halves. 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 or wrap dress 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.
