Something that looks more expensive that it really was. And, depending on the girl, she'll either want something everyone will recognize or she'll want something personal that no one may recognize but she'll know you understand her perfectly.
if shes ur gf plan out something really original get her,her fav flowers and something that she will think of u every time she sees it or if shes really into music write her a song just for her. hope dis helps
Depends on the girl. You could get something like perfume, lotion, ect, but if she's not self confident she could take it as an insult. However the best thing is to find out whats shes into or if there's anything special shes been wanting. If your not sure I'd say just a purse, a stuffed animal, or something to that extent.
Seconded on the gift card idea. Add some of her favorite chocolate or flowers and she'll go nuts. Take her out to do something fun while you're at it. The typical movie and dinner is always nice, but if your not in the mood or strapped for cash get creative. Take a cheap lunch at a bookstore or a coffee place. Stroll down a shopping center and window shop. Swing by a redbox or some other movie rental place. Take her to get groceries so you guys can cook together. It's not always about what you get her unless she's super materialistic, on the flip side if you get her nothing she could think you're being stingy. Remember, she's YOUR girl. YOU are the one who should know her decently well. Take initiative here and remind your lovely lady why she's with you. Good luck!
