Maybe five years ago I went to a wedding for a friend. It was an Indian wedding and the invite said something like “no boxed gifts please.” I’d never seen this before, but I Googled and learned it was a cultural thing and a polite way to ask for cash.
I’ve been to a lot of weddings in the past few years as the vast majority of my friends did not get married young. I personally don’t find it tackier to ask for cash than to ask for gifts, and would rather whatever I gift be put to good use. If anything, I’ve been invited to events that felt like gift grabs, or have heard comments about wanting to be gifted X because X is so overpriced and they’d never dream of buying that for themselves, and been rubbed the wrong way by those.
I’m in my early 30s and have noticed that many of my friends think the traditional registry route is a bit odd nowadays since so many of us couple up a little later and live alone first. Many of us seem to have the too-much-stuff problem.
I say ask for what you want. If that’s a honeyfund, go for it. The way I see it, you run the risk of people thinking you’re tacky no matter what you do.
