What is your budget?
Just bring her out for a nice dinner (it dun have to be expensive,
can go swensen) and also can watch a movie.
If she like accessories, den you can get her necklace or earrings.
You can go to Moshimoshi, their accessories are quite nice. I just
got for my gf's birthday a necklace, a pendant and pair of earrings
for around $55, after 20% discount. There is also cheaper things
too. Msg me if you want to know the location.
At night, you can also bring her to Vivocity 3rd floor, where you
can look over to Sentosa. Nice ambience for a little walk. It can
bring your r/s with her to a closer feeling. Get to know each other
more.
Overall, the a/m will set you back by around $150.
Anyway, just my few cents worth.
