"You ladies look .." - ВЫ дамы выглядИТЕ.... You can say it without verb: 'Дамы/Леди/Девушки вы _ обольстительны сегодня!' (When you say 'Вы' you mean more then one woman, yes?)
I think you will have a success after that words because it will be considered as a compliment.
Of course further conversation (the development of events) will depend from your behavior. I hope you don't think all women will become yours after several compliments. It seems me there is a course "How fascinate women!" I don't think the way to meet with a woman in your country is differ from the way to charm a woman in other Europian (and such) countries. But I can mistake because I never have been in those countries and don't know culture of those people.
If you can to meet a woman in your city and say 'You the woman I see in my dreams' so you can say 'Вы женщина моей мечты' ('вы девушка, которую я вижу в своих мечтах") to Russian girls.
But it depends from situation, I think. For example, you are just funny in a company (в компании друзей) and you flirt with girls. In this situation it will be take as a joke. If you fall in love and say it to the woman which is object of your attention this will be normal.
I hope other girls on MR read your post, because the very fact that you ask such questions is charms
