Christmas, to me, is an understated affair. And having a classic Christmas look for photographs doesn't mean that everyone should be dressed in red from head to toe. Red is a very strong color. It's best to use it as an accent to an otherwise neutral color palette. But hey, that doesn't mean that dressing up for your Christmas family photos should be dull or boring!
For instance, I love that the Allan family doesn't take themselves so seriously... and that they can totally pull off the matching cable-knit sweaters. It helps of course that they have two adorable little girls! Cream colors always look good, especially when most of your family has gorgeous blonde hair and an easy-going attitude.
Most of all, I wish everyone a lovely Holiday and much luck with all the kids being home for a week! ;)
