Outfit suggestions for kids, toddlers, and families:

Wear outfits in the same color family (e.g.: light green and dark green) or have the same accent color.
Don't wear matching outfits. It may seem like a cute idea, but when you look back at the photos it may seem overdone.
Bring several outfits for the kids. This allows you to switch it up and provides an alternative incase of accidents.
Jeans and khakis always work for boys and solid colors always work well for girls.
Another option for the kids is bright colors and patterns can look great .
No sleeveless shirts . Stay away from large logos and cartoon characters on children's clothing.

Outfit suggestions for head shots, professional photos

Bring a couple of clothing options for the shoot -solid colors work well.
Make sure the clothes fit well .
If you wear glasses normally, keep them on for the session .
If you would like, bring some casual clothes to get a variety of shots (business to casual).

Wear what is comfortable to jump, sit, and walk around in.
Have a couple of outfits on-hand
Make sure the clothes fit well and match your style .
Avoid low cut shirts or high skirts .
Guys look good in just about anything. Khakis and jeans seem to go with everything.
Polo shirts on girls don’t seem to photograph well so try to avoid them if possible .
Avoid shirts with lettering. Also sleeveless shirts.

If you want to bring any props (a lacrosse stick, balloons, your favorite hat) with you, you're more than welcome to.
