I get this question a lot especially around Mini Session time. I have tried to describe this in many ways and in the end showing you past pictures of families and what they have worn is probably the best way to answer the question. Years ago whenever people got their picture made they called everyone involved and everyone wore matching things. The same color pant and same color top and things like that. And while that is still done and looks great, there is now another option. I love lots of different colors. I’ve found that layers tend to help the most in family portraits. It’s why I love to do them in the spring and fall. You could just wear different shades of the same color. Or you could pick three colors that look pretty together and some people wear one and others wear the others and then throw in a necklace, scarf, or cardigan with the color that isn’t on your clothes already.
I do recommend staying away from tshirts with things and words on them, unless you are going for a theme of some sort that it lends itself to. No crazy bold, bright prints that will make you stand out above everyone else. Here are some family portraits I’ve done over the years that pulled it together well. And I apologize for the mix up of logo on these, I just grabbed a lot of them off old posts really quickly. Hopefully they can help you get an idea of what looks good.
