The sweater vest was higher quality than I anticipated.  It's a nice heavy weight with a decent stretch.  However, SIZE UP.  The description says to keep in mind that the sizes are smaller than US sizes, and you need to take the seller's word on that.  I'm normally a size medium, and I went up to large.  It's nice and fitted like that (when worn over a button-up shirt), so if you want it to be loose, I would recommend going up at least two sizes from what you normally wear.

I read some comments saying that the stripe was purple instead of blue, and I bought this somewhat hesitantly as a result.  However, whatever problem existed in the past has apparently been remedied.  The blue is definitely blue on my sweater vest, and I'm pleased with the product.
