Hi Marie, how are you going?
To expand on Henry's missive: presents were quite commonly given to young women when they came out - that's the point of the gifts to Fanny Price before her ball.
Both Henry Crawford in Mansfield Park and Willoughby in S&S attempt to give quite inappropriately expensive presents to young ladies: Willoughby offers Marianne a horse, which Elinor tells her to refuse; Crawford is more subtle, as he gives a gold chain via Mary: gifts from a woman were more allowable.
Christmas was an appropriate time for gift giving all round.
In the Regency, candy would obviously not have been given, but I think that flowers or books would still have been acceptable.
If the giver and receiver were wealthy enough, jewelry could be exchanged: for example, a snuff box to a man, or a brooch to a woman.
The point was to avoid particularity and to have reciprocal gifts: a much more expensive present than the receiver could give in return would not be appropriate.
