What's the name of the movie described in the details below?

I once saw a movie trailer this year, where a group of young women met in a livingroom and discussed how to behave while being in another city to attract the least attention. I can't remember why, but there where also white gloves they had to wear. I hope I didnt dream this, cause I really want to see this movie. Can someone help?
Might be possible, that my little "plot description" is wrong, but the gloves have to be in this movie trailer! I can recall them very clearly.

Could it be "The girl in white gloves," the story of Grace Kelly?
