1- Coordinate your outfits
The key to successful photos is to coordinate your outfits and accessories.
Play with color tones, with materials (leather, self, lace, tulle) and with patterns (flowers, special print/text for the occasion).
Determine a color scheme; by choosing tones that complement each other, the images will indeed have a more harmonious and natural look.
To do so you can select two main colors and then add softer tones to accentuate and complete your color palette.
Useful tip: avoid vivid/flashy colors as well as entirely white clothes items, as they often do not give a nice render.
If you have to make a choice, pastel colors, neutral toning, earthly tones can never go wrong!
A great source of inspiration and help to coordinate colors can be found on Pinterest, you can also use this tool
Think about a particular theme (casual in jeans, glamorous with long dresses, fun with tutus) and make sure to match your shoes think of matching your shoes (Spartans, ballerinas, heels, sneakers).
Good to know: even in black and white images, well-matched colors and pattern match will give a harmonious render to your photos!
