Oh my! A Helmut Lang sweater? How did I miss this? I am sorry but it is NOT POSSIBLE for you to have not bought it, and now wear it. I actually think it looks wonderful on you and you will use it a lot. Ok, I will take a deep breath and try to make a more sober assessment. Be back soon.
ETA - I have looked again, and read the comments. Well, I stand by you and your sweater. Perhaps I am just having extreme thrifter empathy, but I would flip if I found that sweater. Frankly, I would snap up the shoes in an instant too. Ever since the skinny cargo fad of a few seasons (years?) ago I have kept an eye out for them, but never really found the right ones. In truth I don't think I would have worn them if I had - but army cargo is not really the vibe I want to express here. I am not sure about the flowered shirt. But the sweater and shoes - sorry, I feel you must KEEP (if the shoes are comfortable).
