Wear something light and airy.
try to avoid red color for this set
Sweater will go great here!
Or you can go with something more dressy like this!
its ok if you add little bit of burgundy color just a little.
If you are going dressing make sure all the shoes matches as well and everyone have shoes on.
You can also try to take the whole family outfit as one outfit.
put out all of the outfits on the bed and take a photo with your phone (flash ON)
to see if it all goes well.
