Do you also get mad when she wears a hot outfit out for dinner? This question doesn't really make sense to me because she's going with you.

Did she pick the costume to please you, or to get some validation here? /r/festivalsluts

This is one of those issues that you don't comment on. Just let her dress how she wants. But this is also one of those issues where you make a mental note.

How a woman dresses in public says something about her. She's free to dress how she wants. It's not your place to say anything or try to control her. But it's definitely your place to have an opinion and treat her accordingly.

Girls dress slutty in public to attract attention. Even if your girlfriend doesn't plan on cheating or doing anything wrong, she's demonstrating to you that she's the type of woman who craves validation from men when she's at a public event like a concert. She enjoys drawing eyes, being looked at, maybe even getting hit on (even if she turns the guys down). And if her past "throws a lot of red flags" like you say, getting the right kind of male attention after a few drinks in a crowded, music-filled, euphoric public place filled with scantily clad hot people where she could slip away easily at any time and claim it was just a bathroom break isn't an ideal situation.

Don't stop her. Just plate her. You don't want a serious, long-term, monogamous relationship with a slut.

You can also agree and amplify in this situation. "Whoa! People are going to be dressed like that?! This is going to be more fun than I thought. If I get any erections while we're there, you'd better help me out."

Then spend half the time you're there chatting with other girls. She'll be too afraid to leave your side to blow other guys in the bathroom.

Why not let her dress slutty? Other dudes be 'mirin but you'll be the one taking her home at the end of the night. Maybe her hot attire will attract an equally hot woman who will want to come home with the both of you. If she does wander off at the festival to jump on a random cock then you've just saved yourself a lot of time and can move on to the next one.

I'd be fine with that, but I like when girls wear slutty bikinis at music festivals.

If your girl looks good, she'll attract male attention either way. You need to be able to handle that (proactively instead of reactively), and putting her in a burka won't help.

Don't worry about it man. If what you are going to is similar to a rave, literally almost every semi attractive female there will be wearing the skimpiest slutiest clothes imaginable. I've been to raves with LTR's and they wear super slutty bikinis (if you can even call them that) and it has never been a problem. Females are strange, they must always feel the need to out-do and out-dress the other females around them, there for they believe they need to dress slutty in an attempt to fit into the scene. I doubt that she wants to dress like that to make you jealous or anything like that. If you have already maintained dominance with her she probably just wants to impress you by being the hottest slut there. AWALT

Tell her, "No, I want you to wear this." and pick something absolutely ugly. Then when she bitches, say, "Ok, fine - how about this." And then give her what you would prefer she wears. She'll be happy to be wearing anything but that ugly thing.

you already answered it. I think if she wants to do it, she will do. If you forbit something to a teenager, he will do it just to show you "yes I can".

do you have any plates? If yes, let your girl go dressed as slut to the party, and take your plate there, too.

should i tell her no?

What will telling her no do? It will stop this specific expression, but not the desire/nature of who she is. Take note of what she's saying about self and act accordingly. What does this mean? Don't expect anything serious from this relationship, do expect her to leave if she meets someone more masculine or cheat on you with such a person.

or...let her wear something that shows of how hot she is, and that as long as she is with you, guys will know what YOU got, that she is WITH you. Now, if her actions tied to what she is wearing seems to indicate she just wants attention from other people, well plate her ass. If she is attractive, people are going to want to look at her whether she is in a bikini or some semi-attractive outfit. Should she be dressed in a nuns outfit? absolutely not. Would you be ok with her showing some skin, but in a less revealing manner as a bikini would be? Again, men WILL be attracted to your GF. There is no stopping that. Maybe she wants to wear something like that for your benefit, because you are there with her.

Bang her before the festival (keep her bikini top on) and blast a load on it.

why would you be bringing her in the first place if not to show her off? any place you're going to hear electronic "music" is all about chicks dressing slutty, people getting fucked up and hooking up. no one is there to listen to music.

honestly i dont know how men can put up with women like that.

maybe why i try to go for older more mature women.

this is a big red flag. theres no bigger turn off than a slut.

At the risk of sounding BP, I gotta ask, are you that insecure? If you are in a disposition to plate her at any given moment and she's thrown red flags then why are you giving her such priority that this act is shaking your frame? Introspect on that and when you're done, don't give a shit, have fun, if she screws up then a girl or two will be there to take her place.

Why have you promoted this girl to girlfriend if she has a lot of red flags? What do hope that to accomplish for you?

If you want to continue a relationship with her for some weird reason and you don't want her to dress like this then use amused mastery on it and agree and amplify. "You're going dressed like that? Cool. I just didn't know you needed that much validation" or some variant on that. Don't try to control her actions but you can let her know you disapprove. If she chooses to not give a shit about your disapproval demote to plate and enjoy her bikini with everyone else.

Look, bikini's look ridiculous unless there is a body of water close by.

Is she asking you or telling you that's what she wants to do? One is her looking for leadership from you, the other is testing your boundaries.

Here's an idea.....why not pair the bikini top with white shorts and cute button up top. Leave a couple buttons open or tie the top. Kinda of a compromise and still sexy.

If you trust her enough for her to be your girlfriend, who cares? Let the world know you've got a hot girlfriend. Like you said, she'll be one of plenty of people without a whole lot of clothing on, and it sounds like it's what she wants to do. Telling her not to wear something because it's too sexual may come off as insecure.

Out of curiosity, why, exactly, would this bother you? Are you afraid she's going to be unfaithful to you? or that you'll have to deal with shooing other guys away? Do you have a conservative view in general on women in bikinis?
