Black and White is classic and classy, it will never date and will leave you with beautiful wedding photos.
(I’m not sure why but black and white wedding photos are always more evocative to me.)
That said the colour combination is easy to work with and source, from wedding stationery, accessories, table settings and favours. You will find it easy to pull together a black and white wedding themed day if you decide to go this way.
Any wedding invitation design can be styled in black and white, the design will give hints as to how formal or casual the day is.  Beneath are a few poplar options of wedding invitations coloured for ideas.

Lollies, the perfect wedding favour, easy to source and you know your guests will eat them and not throw them to the back of the cupboard.
So think about a classic humbug or a giant lollypop as your guests treat.
