Your dance gear is your dance gear, and you should wear it for a headshot session as you would for a dance audition. As for the headshot without dance gear, consider keeping things simple. Avoid layers unless you are going for something specific. Stick to solid but vibrant colors. This means staying away from overly busy plaids and stripes.
As for hair and makeup, you might want to style this in the same way you would for an audition, even though this headshot does not have you in dance gear. In this way, it might help those in casting still see you how you might look as a dancer, even though you are not in dance gear in that headshot.
What to Avoid Wearing for Headshots
There are some things that we can safely say you want to avoid for a headshot, regardless of your profession. For example, sunglasses are probably not a good idea. Turtlenecks are likely also not a good idea. Top hats are probably not good either.
Because headshots are often tightly cropped, you generally should avoid tops that have scooped or similar necklines. This is because it can make the headshot appear as though you are topless. This is likely not what you want to imply.
Dirty or stained clothes should be avoided. Nowadays people often assume a headshot photographer can just Photoshop out a stain. Yes, that is generally true, but it is safer to not assume it. Also, photographers have a saying that “it’s better to get things right in camera” than in post-production. It just removes uncertainty.
If you are unsure of what to wear, bring options you can change into. Also, ask your headshot photographer for advice. You can also do a little homework. Look online at headshot examples that you like and try to mirror what they are wearing. Sometimes, you might like what someone is wearing because of the background color. So, be sure the headshot photographer can closely match the background.
What you wear does matter but, remember that it is usually important to be minimalistic about it. Your headshot should be about you. It is for commercial reasons – to post on LinkedIn for potential jobs, to submit to castings, and so on. So, make sure the person staring at it is focused on you and not that red, blue, and green Hawaiian shirt you somehow ended up with.
All this said, none of these are hard rules. Even if they were, we all know the saying “rules are meant to be broken.” In almost all cases, following these guidelines will serve you best. But they must also match the branding you are trying to create for yourself.
If you want to be known as the doctor with the green lab coat, then be about that. If you want to be the model with the blue and yellow hair, own it. In the end, the headshot is to help create the individual brand you are after, to help land business opportunities you are after.
