Frank Sinatra Themed Wedding

I`m getting married next July outside of Denver...i`ve decided on a Sinatra-themed wedding...and i need help...so far I`ve chosen the music...prosessional, lighting of unity candle, recessional and first dance...we`re having an Italian feast...the groomsmen are wearing fedoras...but the ideas end there...i don`t want to go entirely sinatra overboard, but i would like to add a few more touches...any suggestions?
Also...my girls are wearing just-below-the-knee length dresses in what`s called an "espresso" color...or dark, chocolatey brown...any ideas for an accent color...my gown is "champagne"...or ivory...thanks...
