So after having attended a few balls and wearing a trusty old black suit of mine (usually with a colourful tie of some sort) I'm thinking of getting a new suit for the next one I attend for something different that stands out a bit without being out of place. I like the idea of having a blue suit/brown belt and shoes/checkered shirt outfit in general but I'm wondering if this would be suitable for a university ball? (EDIT: For context, the ball is also "Moroccan" themed though I don't think that's meant to have any bearing on the dresscode.)
The event details say black tie but based on my previous experience (and double checking with the organisers) it appears this isn't a proper black tie event - ie ties and suits of other colours are welcome (in the past I've seen some wacky tie colours and blue and grey suits).
What I haven't seen however (looking back at photos of previous years) is anyone matching a checkered shirt with a suit - I'm guessing this combination may be reserved more for business/less formal situations? I really like how the combination looks, but at the same time get the feeling this probably wouldn't be suitable?
For reference here's the suit jacket I'm currently looking at getting, along with some standard brown formal shoes. The check shirt I was looking at was something like this (same brand, but the pattern was slightly different and I don't think it had a breast pocket). To get an idea of the overall picture I was aiming for, here's a suit combo from the same company. Would this sort of thing be appropriate for my event you think, or should I maybe go with a safer plane white shirt instead?
