Male Fashion Advice

I an lost with what to wear to my wedding. It is a summertime lakehouse venue and I am thinking 100 different things.

Half of me wants to stand out that bit extra and get a dinner jacket/tux. Or else a three piece mismatched set, like matching waistcoat and pants with a different colour jacket.

The other half wants simplicity with a two piece and suspenders.

I like three pieces because they keep you looking together throughout a long day and night.

I am mostly against check patterns and am leaning toward greens like sage or emerald with cream but open to options. Happy with earth tones or natural colours.
