What sort of hobbies does she have is she's not in to sport's?
Work out what she's good at n likes doing then find out if she's missing or needs better equipment ( example she's good at tennis but has a s**te racket.. ( hint get better racket and if you wanted to make it more romantic when she opens it.. Fill the empty space with Rose petals then wrap gift.. When she opens it they fall out or she has to dig through them to get to the gift..) ( it shows you thought about her thus the detail )
Make sure that your recon on the gift is what you think she would really love as it can backfire.. (Ps don't put a condom in a box with petals round it n wrap it.. It might send the wrong message lol)
