I was in Amsterdam the other day and I saw a woman ride past on her bike with the most lovely cardigan, but back in England now and can't find anything the same.
It had a round neck, not those tiny buttons but kind of a chunky one but not overly so, it had a soft brushed kind of fluffy look to it so possibly mohair or eyelash and it was grey, not too light and not dark. Similar to Warm Pewter on the colour chart attached and the cardigan looked similar to the Unison one in the picture but round neck and not as baggy. More similar to the Sezane one but not ribbed/lines. I've looked at so many and none of them are quite right.
I just thought it looked lovely, she had it half buttoned up with a plain white t-shirt and navy trousers and looked so elegant and carefree riding past on her bike.
