Groomsmen Attire for On Ship Ceremony??!

We are getting married on the cruise ship not the beach and I have no idea what my fiance or groomsmen should wear?

My girls are in grey dresses and the colors are grey/orange/white/black themed....we are getting married the day before Halloween.

So I want to incorporate the grey into the guy's attire but not sure.  I don't want them to be too hot but since the ceremony isn't on the beach I don't want it to look to casual.

Ideas please??!!!

We are getting married on the ship too in February. I am hoping to get the guys all in grey suits. Our colors are navy blue, silver and some hot pink thrown in there haha. This is what we're looking at so far. Hope it helps

I like that color...it looks really good!

I'm thinking I may incorporate a suit vest with no suit jacket.  Still undecided though...

This is what my guys wore. We got the separates (pants, vase, and shirt) from jcpenny, groommen's tie from burling coat factory and my husband's suit from Macy's (SeanJohn), tie from an online vendor. They were all on sale, at the time we purchased them. I made their boutonaire and had the add a peacock feather to my husband's.

Wow....they all look so good! Very classy....I love the vest look!  Thanks for sharing...it's definitely helping me get some ideas.

I have to give my husband his credit. This was his idea. I frowned upon it, at first, but it turned out very nice. My brother-in-law thanked us for upgrading his wardrobe. lol

Wow they all look very nice! My colors will be Grey/Yellow/Ivory with accents of turquoise. I REALLY like the groomsmen in vests and the groom in a full suit. It is a nice contrast.
 

Btw did you use the photographer on the ship?  Were you able to get off the ship and take pictures with your bridal party?  I'm just wondering about the flow of the day and I don't really want all my photos to be on the ship.  Any info would help!  Thanks:)

you could go either way!

I love that picture! They do look sharp in their suits.
