Tie and socks

Hello! My two guys (fiancé and best man) are in navy suits. The groom will have an ivory, faint floral tie, but all ivory, to complement my dress. His pocket square will be the same although I keep reading they should not match?
What color socks?
And for the best man (our only bridal party on the groom’s side, so we want to look uniform) is a solid ivory tie ok? I don’t want him in floral. Then what color pocket square (ivory?). I feel lame matching it all. And what sock color?
My MOH is in a blue dress darker but lighter than navy.Originally we were going to have the best man in a navy tie. I also have a blue tie that matches my sister’s dress exactly and pocket square but the blue on top of the navy suit was just kind of blah.Ideas?
