Black Double Take Double Breasted Blazer by Aday, who makes the best clothes for work / life / travel (selling bc I have too many of them!) Blazer has two closure options but also sits so well open - has a little A line shape to it and so sides flare perfectly. Arms are roomy enough to layer - I have worn this over a long sleeved blouse for work trips and flights and it is incredibly comfortable and stretchy. Super modern, sleek, in perfect condition. Size small fits very true with good shoulder room. Brand is highly sustainable!
