Hugo Boss dress, brand new

I put size M because it's tagged as GB 8 (which is US 4) but feels like on a bigger side of 4 (not really my size which is between 2 and 4). The dress is super stylish, but never ever worn except for trying on. Tag never removed. I kept it for a long time in a closet hoping one time to wear it but in two years it never happened so I'm ready to let it go. Hugo Boss branded hanger is included in price.
