Handknit Aran sweater from Harris Knitwear.

When we were in the Aran Islands, Sean bought one of these from young woman who was sitting in a tiny room packed floor to ceiling with sweaters she had made, and even as we spoke to her, she was methodically knitting while she rocked her baby's cradle with her foot. She took one look at Sean and pulled off the shelf a sweater with longer arms and a narrower torso that fit him exactly. It's too warm to wear on any but the coldest, dampest days.

It's only a myth that each fisherman had a uniquely patterned sweater to help in his identification in case he drowned and washed ashore.
