It could be that she doesn't get enough appreciation from you or that she just likes attention which isn't bad. Perhaps she likes the admiring stares coming her way which probably doesn't mean she is looking for something else on the side, or could be she missed a stage in her teens or youth to explore about her looks and appearance which means she might get over it soon, and also could mean she just likes to look sexy and has no idea it offends you. Try having a chat with her and see what her reaction could be. Wouldn't be that bad to try if you both love each other.
