What you need to know about preparing for your headshots:

1) Style
     * traditional (portrait orientation, more dead space around the edges, posed, etc.)
     * modern (landscape orientation, tighter crop, more relaxed feel, staged / setups)
     * light / dark / color / landscape (nature / industrial) background

2) Outfit
     * long sleeves
     * simple / bold color schemes
     * layers
     * jewelry / props 

For as simple as a headshot session may seem, there is, actually, a lot to consider when planning yours.

Who is it for? Are you self-employed or do you work for a corporation?

If self-employed, does your business have a brand that you'd like to follow?

Does your employer have lighting / background setup requirements to ensure consistency? 

With outfits, I always recommend long sleeve. Blazers (suit jackets) are my go-to - I love how professional, yet forgiving, they are. The key, however, is making sure they fit properly. You can, actually, find pretty decent ones, that don't break the bank, at places like Ross or TJ Maxx, if you don't have any at home, and they go with everything. I even wear them with graphic T's, so, unlike the bridesmaid dress you bought 10 years ago and will never wear again, a good blazer (suit jacket) is a worthwhile investment, especially, in a professional setting. 

Simple color schemes - the fewer patterns, the better. Obviously, for a headshot, our objective is to bring attention to your face, not your clothing. Busy patterns draw attention away from the face, so I highly recommend solid colors and avoiding reflective materials (silks, etc.).

Layers - this adds variety and texture. It's another reason why I love a nice business jacket. However, it can be a simple vest, or blouse over a dress shirt / nice tank top as well.

Jewelry - I love statement pieces, however, it can be easy to go too far. If you want a bold earring, go simple with necklaces, vice versa.

Makeup - keep makeup simple, but just a tad more bold than you're used to. We want your headshot to look like you, but the camera will not pick up everything that you see in the mirror. Lightly filled in brows with a simple set of false lashes can really make your eyes pop. 

That being said...it took me 30 years to master false eyelash application, so if you're not comfortable with it, no worries at all! I can either help, of we can go without. I just, personally, love the look, so I recommend it if you're open to it. :)
