SOS - NEED WEDDING HELP

Em

I'm in meltdown here. We get married on Friday & there's so much left undone.

a) Fiance has no tie. He's wearing a navy suit. What colors could I go with?

b) groomsman wants to wear his black suit. Would this look ok with hubby's navy?

c) I've just realised I've got no loop in the train of my gown. It's got a 60cm train. Do you think I could get away with it?

Thanks in advance my lovelies x
