If you as a person are already classy, elegant and modest, then the lingerie that you wear is going to complement that.

You want it to still look classy and elegant - as much as it can look, anyway. It is still kind of gaudy, but you don't want it to be extreme.

I wear women's leggings under my clothes, but no lingerie.

How classy is it for me to wear these pink tennis shoes with my tux?

I'm a very modest person.

Because I'm shy and a bit quiet, I think people assume I'm an elegant person.
