Looking for a turtleneck that's a little less warm than merino or cashmere to layer under jackets/blazers/dresses. A cotton blend would be great -- a touch of wool/cashmere/silk is fine. Would really like it to be ribbed and quite fitted, and hold its shape well. In other words, a step up from a plain old jersey turtleneck a la Lands End/LLBean. Nothing makes me feel less fab than a plain old jersey turtleneck. Also not interested in the tissue weight ones from JCrew/Madewell. Too thin. This will mostly be a layering piece but needs to stand on its own if I take the topper off.

Hoping to add one black and one in a bright/rich colour. Ideas?

I'm thinking of trying these two -- one from Club Monaco, one from Boden. Does anyone have other recs for me to try?
