Is it normal to be jealous in this way?

If she is doing it, knowing that she is bringing that attention to herself, and that you do not like it, then as a loving partner, she should put her feelings for you ahead of her clothing.
If she is not willing to change, then she is not changing such things as clothing for your emotions. This would imply she cares more about her clothes and how people see her than she cares about your emotions and you completely.

You can't force her to not wear cetain clothes, she is the one that chooses that, but if she puts clothing before you, then it is completely understandable and completely your choice to leave her to find someone that would take your feelings in to consideration more than their clothing.

She may not know you feel this way. If you have simply said "don't wear those" without explaining why, then she may not know of your feelings on the matter, in which you should explain. If you already have, or after telling her your feelings of why that she continues, then my advice would be find someone that cares more about your feelings than her clothing and how everyone else sees her.

I find it safe to assume she's always done this, also that you've always been the jealous type. You set yourselves up. You can't expect each other to change, unless you both feel like you want your own selves to change.

If you're worried about her wanting attention, don't worry too much. Girls do genuinely like to dress how they feel is pretty simply to feel good about themselves. I know a lot guys want it to be for other reasons, but dressing up is more for the girl doing it, not the guys seeing it. In most cases, anyway. Unless she's given you other reason to be jealous, this case it probably where it's at.

Maybe some additional questions:
-For males: do you get jealous, feel uncomfortable or have painful feelings when you think that other men are sexually attracted to your partner and having sexual fantasies about her? I mean, even if she does not reciprocate their interest and does not flirt with them.
-For females: Do you think that your boyfriend gets jealous when you (also unwillingly) attract the attention of other men?

If she dresses provocative... men are going to naturally get turned on by her and will hit on her...hopefully she won't do it while partying...cause more likely she will end up sleeping with someone else... She evidently does like the attention and likes that people think she is sexy...and women check out men also....

If my boyfriend dressed like that, I'd be concerned for him but I'd still trust him to be faithful to me.
