Silver gray suit+light gray shirt+blue twill tie+beige vest ~ ~ not eye-catching but can't be wrong.
PS: Don't wear a vest if you don't feel particularly cold. It seems a little strange to match. And because your suit is fashionable and dazzling, it is not suitable for matching with common vest colors such as brown and black. There's nothing wrong with ties, but it's best not to wear dark ones. It looks a little heavy, so the shirt must be light, or it will be messy and elegant.
