First off, thank you for trusting me with your family photos! I definitely don't take this opportunity lightly.
The first step to good photos is having beautiful outfits!
Keep in mind bright colours like red, yellow, blue, etc. are very distracting in a photograph. While they look great in person, they photograph very harsh. You definitely want to avoid everyone in jeans, or both mom AND dad in jeans, etc. Matching = X, coordinating = *heart eyes* lol
I have put a little bit of a colour palette below for you to reference when choosing outfits.
Note: Flowing dresses work better than tight dresses/skirts, no running shoes would be ideal :), and rather than jackets, think of layers - scarves, cardigans, etc. work better than winter jackets :)
However, remember that I am always here for you to send photographs to of outfits that you're thinking and I can help you put together your outfits if you need!
