Tres's /Groomsmen Attire?

Here are some ideas I found for Tres's Outfit...what do you think?

LOL I did not just choose this pic because Ryan Reynolds is in it ;)

 

This is an idea we had for the groomsmen to wear, we even maybe wanted Tres to wear something like this (Not the black suit, I'm referring to the white top & linen pants). But I don't know if my dress is too dressy for it.
