Why don't you play it safe and dress like a goddamn adult? I highly doubt your friends would be inviting you to lunch to somewhere where jacket and tie were *required*, so maybe just wear a pair of nice pants and a cardigan? It's a classic look without being too casual or too dressy.
Like the first two dudes. Unless you're some dude who always wears trash wigger shit, then you're fucked.
