Interviews aren't the place to re-invent business professional fashion norms. I distinctly remember a woman that interviewed in snakeskin high heels in the Midwest. No, we aren't in California or San Antonio. Leave that crap at home.
Similarly for guys, don't re-invent the wheel. Navy or charcoal suit, dress shirt, tie. White or blue dress shirt without a weird pattern. Brown or black dress shoes (Oxfords) with a matching belt. Don't wear a bowtie, for the love of God. You aren't a pediatrician in South Carolina. No weird-colored suits, no neon dress shirts from Express. Just blend in. If you don't have one, just go to Suit Supply and buy their entry-level navy suit and get some dress shirts from wherever else. Oxfords from Allen Edmonds (Park Avenue) or something similar. Don't wear loafers or boat shoes or cowboy boots with a suit.
For pre-interview social events, I just wore chinos with a button-down shirt and casual boots. Seemed to fit in as most of these places were at a bar or one of the resident's houses. Look comfortable but smart.
