Odd shape
"These are odd to wear. The legs run long, and the elastic in the waist is pretty loose, in line with the fabric, so they don't stay up well. There is a low hanging bulk of fabric in the back which brought back memories of being a child in a very worn set of swimmers with a saggy perished bum which my dad teasingly called the "poo catcher". They're warm, if you don't mind lots of saggy fabric bunching in places and no way to hold them up"
