Miley Cyrus is nineteen and not afraid to dress a little bit risque ... even when going to dinner with her parents!

The "Can't Be Tamed" songstress went to dinner at Casa Vega in LA with her beau Liam Hemsworth as well as Billy Ray and Tish Cyrus.

But we couldn't help but notice that the former Hannah Montana star was wearing a see-thru top without a bra. Come on, Miley ... we have a feeling this wasn't by accident.

What a wild child!
