WHAT TO WEAR
First, decide what kind of feel you are going for. If you are wanting a warm color palette, consider mustard, brown, rust, cream, burgundy, and taupe. If you want a lighter, more pastel palette, choose clothing that is neutral and light toned. Colors that would look great for this are cream, white, beige, gray, muted pinks, coral, rose, and light blues. If you are looking for a more dark and moody look, choose some moodier colors, but mix in some lighter colors with it to keep it from looking TOO dark. Another idea would be to choose a couple pops of color, but keep the rest neutral.
PLEASE DO choose well-fitting clothing and something that you feel comfortable and confident in. I recommend starting with mom’s look first, then build the kid’s outfits off of that, and then find something for dad that coordinates last. You want to coordinate, but not match. So I wouldn’t recommend just saying “We’re doing emerald green,” and then going out and getting tons of the same colored shirts for everyone. Get a textured knit sweater in green, a cream color shirt for another, a lighter colored floral dress for another person, a mustard lace dress for another, etc.
Here are some great examples
The goal is to look good together without being matchy-matchy (avoid this!). Change up textures and prints.
AVOID! Stay away from thin, close together stripes (it has an odd effect in photographs), small plaid prints, large logos, cartoon characters, or words on your clothing, as it detracts from the main subject of the photo: you.
Stay away from using too many super dark colors, as it makes photos look dull (especially black). Also avoid neon colors at all costs, they are super distracting and can create a strange color cast on your skin. Here's an entire article on the subject of what not to wear.
Don’t forget about shoes! This is usually the thing most people think about last, but it really makes a difference. Avoid athletic shoes and shoes with neon colors (looks at those soles!) Wear shoes that go with the style you are wearing. For home or on the beach, and in that case, forget shoes!
CLIENT CLOSET! I have a client closet full of beautiful dresses, rompers, etc for clients to borrow during their session. Please check it out and let me know if you need additional sizing info or if you want to set up a time to try something on.
