Bridal shower gift help

My cousins bridal shower is in a few weeks and I’m unsure what to get her. On the invitation it says they would really appreciate a little something toward there honey moon in Greece. I still wanna get her something besides money. So I was thinking of getting these made for the flight to Greece still something towards the honey moon in a different way ;) any thoughts on this if it’s a stupid idea or if anyone has any other ideas ?

The sweater and leggings lettering could match when I get them made
