Hi hive!  I'd love your advice on what the guys should wear.  We are getting married outside (fingers crossed for lovely weather!) at a historic estate.  Our colors are navy blue and yellow.  I am wearing an ivory dress, my girls will be in knee length navy chiffon dresses, and we will have yellow & white flowers.  FI loves this CK gray tuxedo from mens wearhouse with an ivory shirt and yellow tie (& maybe navy ties for the other guys).  I've never really seen gray tuxes before, but they looked really nice in the store.  I think with the wedding being nice but not super formal, and being outside in June that the gray will be nice, but I've just never seen it before so it makes me a little nervous.  I've attached a pic of my dress, the tux, and an example of the bridesmaid dress/flowers.  What do you think?!  As usual, thanks for your sage advice :)

Thanks :)

I love the gray! Maybe I'm biased because the our guys are also wearing gray but I think it looks great for an outside wedding and it's different from the standard black.  Our colors are gray and yellow with teal accents.  The groomsmen will be wearing charcoal gray suits with yellow ties, and my fiance is going to wear a lighter gray suit.  He isn't sure if he wants to also wear a yellow tie, or go with a white tie.  The bridesmaids will be wearing gray dresses with yellow bouquets.
