I believe there is no ideal body shape. Whatever shape your body is, that's perfect for you. I do believe in dressing in silhouettes that flatter your figure—and staying away from clothing that does not radiate your confidence. With that said, let's talk about dressing for your body.
Let's start with the 4 basic shapes.
Rectangle: You know those billowy tops? They were created based on this shape! Shoulders and hips are the same size and the waist is undefined. Usually called the "boyish" figure or "waif" look. Kate Moss, Victoria Beckham, and Cameron Diaz are famous folks with this frame.
Inverted Triangle: Creating balance in the broadness of shoulders and full bust with narrow hips and undefined waist is the goal for this silhouette. This is also know as the "apple" shape. Sherri Shepard, Catherine Zeta-Jones, and Demi Moore are Inverted Triangles.
Triangle: Songs about derrieres were created with this figure in mind. Shoulders and bust are narrow and small with a well defined waist and full hips and thighs. Also known as the "pear," Kelly Clarkson, Jennifer Lopez, and Kristin Davis play into their Triangle shapes well.
There are petite hourglasses and full-figured rectangles. There are inverted triangles that are very slim. These "shapes" are just a guide for dressing to complement your figure. After 10 years in business as a wardrobe consultant, I've learned that the multitude of variations of body shapes are as endless as the hues in a sunset.
