blue blazer, jeans and either white, oxford blue, or pink shirt = always chic .must match belt and shoes for elevated look but if its a casual night that is cool enough for a blazer, throw on flip flops no problem
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.
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.
