How does she typically dress for you?
How do you like her to dress for you & does she typically do what pleases you?
A woman who is attractive is going to get attention. Period. If she dresses in any sort of nightlife outfit.
Sexy is often less (revealing) is more (intriguing). Like Mazer's plate. If a woman with a great body wears something that flatters or accentuates her figure...men are going to notice. The bust does not need to be spilling out. That's too much.
I hate the cut off denim short shorts the girls wear now where you can see ass cheeks. It's vulgar. And I have the body to wear stuff like that...but vulgar is vulgar and sends the wrong
message.
Women who are truly sexy do not need to flash flesh. That gets attention from men, sure. The wrong kind. It's much more interesting to show enough figure or leg or neckline etc. but also enough coverage that men realize there is MORE than meets the eye. It's sexier to show off your shape as a woman than to show too much skin.
I wear very tight dresses that show off my body for going out but without showing too much skin. Google Herve Leger. Those are the dresses my man prefers I wear, with a good pair of heels that accents the legs. To look great in dresses that tight you have to have a great figure. There is nowhere to hide flaws.
My ex used to like micro-mini skirts. Those show lots of leg. But if I wear something that short, I wear a modest shortsleeve top (snug but not showing midriff or cleavage) that keeps my shoulders covered.
A good rule of thumb for a chick is show off one thing and keep the rest more modest.
It's more interesting to reveal less and intrigue more. It's sexier & more playful. It's classier. The tough thing is it's hard to teach someone "class". Either they are classy or they aren't. People always think they have good taste and nobody takes well the possibility that they don't. That message never is well received.
If your chick, OP dresses more revealing when she goes out without you & less revealing when she goes out with you, that's a potential issue. All you can do is state your preference in a neutral way and observe what she does.
If she looks for your guidance & approval, that's good. If she tells you you don't have any business telling her how to dress...that's less good.
All you can do is apply your standard & vote with your time & attention.
