Go for an olive wool blazer and grey plaid dress pants for a proper sophisticated menswear style. Our favorite of an infinite number of ways to finish this getup is dark brown suede tassel loafers. Keep this ensemble in your front hall wardrobe when warmer days are here, and we promise you'll save a ton of time getting dressed on more than one occasion. So if you're hunting for style inspiration for dressing in your 30s, this pairing is definitely worth saving for later.
