1) Teddy bear.
2) Make up products.
3) Sex toys.
4) Cheap Chocolate.
5) Flowers.
If you really want to gift flowers to your girl, you must send the flowers to her office or her house, because girl love to show off the flowers to her working-mates / family members. Do not gift her flowers when she is walking at outside, because she will feel it is very inconvenient to hold the flowers while need meet some friends, shopping, having dinner, it is very inconvenient for her to hold the flowers all the ways, thus she will feel it is annoying and feel bad.

If you want to gift chocolate to her, please don't simply buy a cheap chocolate bar for her. You must buy the expensive + very beautiful chocolate. The box of the chocolate must be very nice, make sure she love the box, she might use the box to keep her things such as diary book, jewelries or sweets.
