I think I’m a bit torn: on the one hand, I really like the pants; good fit, a nice cuff and short as hell. The shoes, fine, I could get behind them, but honestly? This might be just my oppinion, but the worn-out look of the blazer really bugs me. It seems to me like it should have ended up with goodwill about a year and a half ago. Also, unbuttoned button-down collar is a no-go in my personal book, and I think a black belt with brown shoes and bag should be a punishable offense.
The shirt-and-tie combo would be nice, especially in summer, if the collar were a bit more formal, i.e. unconstructed kent, but again, an unbuttoned button-down is just hateful.
However, since I want to end on a positive note, I like the combination trousers, pocket square and lapel pin. Overall I think this is not a good look.
