Re: invitations, the price of a stamp is pushing £1 now. We're going to a wedding later in the year, where the invitation was an email, with a link to download an app (Joy) which has the details on. This went down three ways:
Less techie rellies, generally 70+ - what's this all about? What's wrong with a card invitation? Where and when is this wedding?
Moderately techie - couldn't they just put the details in the email?
Youngsters - oooh, an app!!
I've recently got a new phone and have had to download the app again. I've forgotten my password, app is not being very forthcoming coming with a reminder...
You could cut costs on invitations by sending traditional cards to less techie folk, and emails to others.
The only advantage to app seems to have is that the b&g can add details to it as time passes. At the moment we don't know where the reception is yet! I'd have thought that most people planning a wedding would actually know this. (Maybe this is an old fashioned view).
Other potential cost savings - do your own hair and make up ? Pot luck supper? Shop bought cake. Don't go OTT on decorations. I've been to 20 or so weddings and could not tell you how the venue was decorated for any of them, or whether the chair covers matched the groom's tie, but I could tell you who had the best food by far, and who didn't account for non-standard diets and whose reception collapsed after a couple of hours when everyone went to the Chinese takeaway because they didn't put on any food for guests at all.
We had an amateur band from a local college. Now I guess you'd use a phone playlist.
We did not have any photo booths/sweet trolleys/doves/balloons (autistic nephew) or many flowers (hayfever throughout DH's family) or personalised matchbooks/napkins/champagne glasses.
My lovely, now-ex BIL, lived in London and did a booze run to Calais for us. (My DSis got divorced, not me).
We did have friends, family, children (several parents chose to leave them at home, but all were invited) and plenty of food, drink and photos. Also a prof photographer, but this was before everyone had smart phones. Maybe friends with phones could be used instead of a prof photographer, but I'd still designate someone to gather people into appropriate groups and ensure that a few "key" pictures are taken.
My dress wasn't a traditional wedding dress. It was an evening dress, designer @ Harvey Nicks, but lots of brilliant high street dresses around. DSis wore a slinky nighty and jewelled flip flops!
I won't take credit for this, but one friend combined table decor/place names/favours by growing herbs in little terracotta pots, and chalking names on the pots.
