This is a Sunday brunch with the guys or family outfit! I feel like you don't have to wear dress pant to wear a blazer with a dress shirt. Just throw on some plain, simple jeans and add on that beige blazer with a neutral color dress shirt.
Because you’re going to be dancing for most of your dress-up time, you’ll be pairing blazers and jeans a lot. For that, you’ll want more casual blazers. Also, the sweater pairing is sharp, though probably too warm for the dance floor.
Casual and stylish — Navy Jeans — Brown Leather Belt — Brown Leather Brogues — Burgundy Paisley Pocket Square — Burgundy Tie — Beige Blazer (think Trumaker Mitani) — White and Navy Gingham Dress Shirt (think Trumaker Whitney)
