If you are also getting longer length shots, think about bringing some form fitted clothing and some flowing pieces as well. If you are have a portfolio shoot, do you want to incorporate any street looks? This can include shorts, chunky boots, jeans and crop tops. Wear something comfortable and that you can easily move in as you will be working on action shots.
Only the top half of your body is visible in headshots so pay most attention to what will be featured in this section of the image and bring more choices for the top half. If wearing a jacket, keep it fitted and think of a top/shirt underneath that will add a pop of colour. Primary colours (blue/yellow/red) work well as do jewel colours (jades/pinks/silver/gold).
Avoid clothing with busy patterns. Go for solid colours. Form fitted clothing is best.
Layers are good too so that you can mix it up quickly to give a totally different look.
