I am still debating on if I want navy blue or turqoise bridesmaid dresses. I originally wanted turqoise wtih hot pink and orange flowers but now I am leaning towards navy blue with the same colored flowers. One of my major concerns right now is what color tuxes the guys would wear if I did navy blue? Does anyone have any pictures they can show me. I know some people say black tuxes and others say grey.  I am having trouble finding pictures online and I am a visual person! 

Also, for chair covers I liked how the turqoise bows look better...but if i did navy dresses do you think that hot pink bows would look good and flow well? Since that will be a color in my flowrers?

Thank you in advance for any help!
