Miss USA 2009 contestants

Miss USA contestants in evening wear. Miss USA contestants in bikinis. Overall, a terrific gallery.

"There she is, Miss Amer"—oh wait, wrong show.

To ring in its 58th year, Miss USA will be crowned live from the suitably classy Planet Hollywood Resort and Casino in Las Vegas. In honor of this most auspicious of televised events, we’ve assembled a gallery of our favorite female 'state-estants'—first in their evening gowns, and then in nothin’ but their swimsuits, sashes and Vaseline-intensified smiles.

So undress them with your eyes, then click ‘next’ to undress them with your mouse. Finally, the Internet has reached its true potential.

"Miss USA 2009" airs live on Sunday, April 19, at 7 p.m. ET/PT on NBC.
