A Shardigan is a Cardigan that has a fake shirt beneath it - Very similar to a Shumper.

"Phil ? Is that a new Shirt and Cardigan you got there ?"

"Nope, it's a new Shardigan !!"

Get the Shardigan mug.
A shardigan is a combination shawl/cardigan. One side is slightly shaped and may have a loose sleeve, the other is flat and worn wrapped around the shoulders.
I bought all this yarn at the craft fair, but I'm never going to get around to finishing my shardigan.
