I'm not really feelin' that tie personally. It's a nice tie, but it's too bland. I'd definitely rock something a little brighter/more lively to a spring wedding if you don't want to blend right in with everyone else there but that's all on you.
If you could find a dark maroon shirt that is similar to the maroon in that plaid, that might work...hard to say without seeing live. white couldn't be any more boring...you'll look like every other asshole that wears a shirt and tie to work every day...stay away from that shit.....yeah, that's all I've got to offer.
