*** remember to stick to either all light or all dark.. but dont do both. Dark bottoms are slimming :)***
Try and keep everyone’s outfit in the same tonal range. For instance: if your kids are wearing light colors or pastels, make sure that the adults wear light colors as well. Try light blues, greens, coral, or any pastels. Your family does not have to dress exactly alike in order to look connected. Try laying the clothes out on the bed to see how they look together ahead of time.
Other than that... keep it simple... and don't forget to HAVE FUN!!
