Echoing others that anything can be beautiful in the right context.
IMHO the pin & cableknit sweater shows the scarf off in its worse light.
I wonder how it would look with a very plain neutral background (sweater, blouse, jacket) or yellow background so that the black would pop or veiled under a gauzy black scarf so it's not so strong or ... yellow/green shoes/bag/belt/hat to move your eye around.
If you don't have have the right companion clothes, and don't have a lot of that bright yellow- green in your wardrobe,
do you want to invest your attention in finding a way to wear it?
There is something intriguingly pretty about it but it's also strong and hard to work with, (especially if the yellow and green are not your favorite colors ) so it's okay to pass on, and yet it's small enough that,
if you like it, keeping it in your closet might not bring too much clutter. But Ugly isn't the right word for it.
