I haven't read all the comments, but I did see your reply that the sleeves are comfy, they're just too tight to look good with layers underneath the sleeves.
I think the color is great on you, and that's a beautiful outfit you put together. I think there are certain garments that have such a high happiness factor, that it doesn't matter if you can only make one outfit out of them, if that one outfit makes you feel like a million bucks!
But what I am thinking is, if you have a brightly colored, dark, or denim pencil skirt, this sweater could hold its own in a rockabilly, bombshell, Rizzo-inspired way.
Or keep everything in this outfit, and swap out the shoes for a second outfit.
