This is a request about an Irish wedding in Ireland, so UK wedding principles do not apply!
16yo DD is going as her bff's plus one to bff's sister's wedding. They will be the only under 18s attending (so DD is invited specifically for the bff, no cousins, etc there for company, if that's relevant at all). What wedding present should I give her to give them? €100 in a card ok? Or should I go a bit higher?
