Choosing a Look.
While you do not want to match, you do want to pick clothing that is in the same general family of colours. This way, the pair of you will coordinate, rather than matching or clashing. Wear clothes that fit your body, with very simple patterns or which are solid in colour. At the same time that you are choosing your setting, think about whether you want a casual or a dressy shoot. A little black dress paired with a slick three-piece suit is a great way to ensure you both look your best—but keep in mind that you will be sitting, standing, lying down, and even running and jumping during your shoot.
What do you absolutely want to avoid? Horizontal stripes—no matter how thin you are, they will make you look wide. Loud patterns will overwhelm you and wearing the same colour from head to do will consume you. Big logos, clothing that is skin-tight, anything very short or really baggy, and very low necklines should all be avoided.
The bottom line: wear something that you look great in, but which you are also comfortable in. When you feel good, you’ll look good.
