I always like a bracelet-sleeve blazer, albeit possibly because I’m on the border of petite and regular sizes. Still, it can be a lovely look for spring/summer/fall. I like the double lapel and double hem, as well as what they call “the smart back vent.” (Interestingly, they do note that you can machine wash the blazer!) It’s $150, available in both regular and petite sizes. White House | Black Market Bracelet-Sleeve Seasonless Blazer
