I need help with a Shoe decision

Hello everyone.
Sooo me and my fiancé are invited to a wedding.
I bought my self a imo nice and fitting summer suit but I cant decide on what shoes fit best.
I want to go for a relaxed vibe with sneakers, the ones I bought were the Puma Caven but I think there to bland in all white.
What do you guys recommend?
Blue shoes, brown shoes or plain white?
Thanks for everything in advance!
