Hi there, and thank you for your answer in advance!

My question is quite simple or not... actually i´m getting married in november, and my girlfriend and i were thinking to dance some classic song from 50-60s, maybe a Frank Sinatra song, maybe "fly me to the moon" or "under my skin"... i´m in Argentina, so i just need your advice to look for the steps by knowing the song´s style (we don´t know which is the right frank´s music style )...so it´s easier for us to look for something on the internet or in this webpage, which we think is great!

Frank does some of the best Foxtrots ( and occasional Quickstep ) to dance to.
I suggest for your event, stay with a simpler social American style foxtrot ( remember, with a long dress, turns are problematic )

"Just the Way You Look Tonight" is pretty common for Fox Trot, and is used in studios quite a bit when teaching that dance.
"Blue Moon" would be a little slower, but still a good Fox Trot. The same with "Summer Wind."
"Under My Skin" works too, I believe. I don't recall dancing to "Fly Me to the Moon" in some time, so I can't say for sure on that one.
Oddly enough, "I Won't Dance" which is really a cool song, is a little tougher because its tempo is not the best for Fox Trot.
If you want a similar crooner with great Fox Trot tunes, Bobby Darin's "I'm Beginning to See the Light" and "Beyond the Sea" are lots of fun for Fox Trots.
But you absolutely cannot go wrong with Sinatra. He is the greatest.

Germany's Horst and Andrea Beer did a great Rumba to Sinatra siging. I DID IT MY WAY played exactly as it was recorded.

A young, current, and one of the most popular artists, Michael Buble, has some beautiful foxtrots such as below. Michael would be my choice of artists. I suggest going into iTunes, search for Michael Buble and listen to his music.

Also, I would suggest that when you select the music, that you look for a song that fits your personalities. If you have a problem with music timing and beats, then a slow song would probably be best selected. Choose a song that fits your level of dancing.

FOXTROTS:
FOR ONCE IN MY LIFE (very slow);

COME FLY WITH ME (medium pace with nice intro);

HOW SWEET IT IS TO BE LOVED BY YOU
(while this is a swing, it is a medium paced and bouncy);

I'VE GOT YOU UNDER MY SKIN
(medium paced, bouncy)

A popular song, THE WAY YOU LOOK TONIGHT, is also a great RUMBA by Michael Buble. I believe that Sinatra does the same song in a Foxtrot.
