Oh well you do seem to be right about the merino question- you sure did a lot of research!

Too bad the sweater is not right for you.
But...it seems you did get a few other pieces of merino that will be quite useful and cozy, so that's ok.
Sometimes I think it's the inner layers that are the most important. If one is wearing a luxurious merino or cashmere base layer, to me it feels kind of chic to throw a favorite worn baggy thrift shop sweater over it. Of course, baggy isn't so good for biking, but it's nice around the house or going to the supermarket.
