Ways to dress more feminine?

I want to dress and look more feminine, because it's appealing to me. But I have a hard time picking out good, attractive clothes that look feminine. And when I try them on, there's either too much boobage, it's to short or tight for my taste, or I look like a box. I want to look classy and elegant and graceful, I don't wanna wear revealing, super tight clothes that look weird on me.

I know that right, more revealing clothes are in. But im not into trends. Where can I find good, elegant, modest feminine clothing?
