Jeans with navy blue tops and a touch of red. I reckon those colours look great in photos!
Ooh, I like that idea probably have lots in those colours too.

Maybe DH and DS1 in a navy polo and jeans (we have those) , a navy top and jeans with a red necklace/beads for me and DS2 has some cute max and tilly navy overalls with a little red pic on the front, worn with a red onesie underneath?
