Coordinate outfits. Everybody in the portrait should wear items that complement each other in style and color. It is not necessary for all clothes to match, but they must make sense together. If grandpa wears a suit and tie and grandma wears shorts and a t-shirt, the portrait may look unbalanced and poorly planned. Stick to solids and subtle patterns. Bold stripes, large designs and polka dots stand out and tend to draw attention from the portrait's subject. An eclectic mix of patterns can clash and reduce the quality of a portrait. Wear colors that translate well through photography. Dark colors like navy blue, black and earth tones look especially nice outdoors. White clothing can get lost against a white background, and dark clothing against a pastel provides nice contrast. Bright shades of yellow, orange and pink can alter skin tones and are not ideal for photographs.

Women should keep jewelry to a minimum
and wear natural-looking makeup. You may want to wear slightly more
lipstick or blush than usual so it shows up in the picture. Take some
spare makeup with you and ask the photographer whether you need
adjustments.
#5
Large, baggy clothing make people look larger in photographs. Wear
clothes that fit properly. In addition, skimpy or revealing clothes are
inappropriate dress for a family portrait.
Men should shave before the portrait and trim moustaches or beards. Get a
haircut at least two weeks before the portrait. If you get a bad cut, a
couple of weeks will allow your hair to recover.#7
Newborns and babies look best in thier birthday suit.. but if you would like for your baby to be covered we suggest you use plain clothing without polka dots, busy patterns and plaids.or even a diaper cover.

I tend to like bright colors on little girls, and i like seing little boys in nice plain colored dress shirts and kahkis.usualy colors that accent the eyes.
