I wouldn’t buy that for a 5 year old. Maybe a very light flower cologne if she really was dying for perfume - M&S do a Lily of the Valley, or used to.
Having said that, I have a 5 year old Gdd and have previously bought her a children’s make up set and for Christmas I’ve got her a children’s ‘designer’ nail art set, with polishes and stick-on bits. She adores anything like that.
Funnily enough I’d never have bought such things for my own dds - I’d have thought them disgustingly tacky!
