When it's your girlfriend's birthday, you must prepare in advance and give her whatever she likes. If you buy something expensive, she wastes it if she doesn't like it, and it's not too expensive to give her a gift.

Then you can give him a hand-embroidered silk scarf, which is necessary for girls.
