Hey ladies, I'd like a little menswear advice for our wedding:
This is my dress:

And the wedding is outdoor, relatively casual. FI owns a lightweight black wool suit, which he will be wearing for the wedding. I am having some trouble figuring out the shirt and tie. Our wedding colors are grey, yellow and black.
FI is laid back and, bless his heart, not super trendy. So a lot of the more popular ideas (Chucks instead of dress shoes) are really not his style.
I bought a few plain white shirts... and they look a little too formal for our wedding. Any thoughts? White and black windowpane shirt? Black and white striped shirt?... Then what to do about the tie...? No tie?
Thanks ladies!!
