Heian-period nobles wore creased eboshi hats.
烏帽子 is the general term for the traditional courtier's hat, while 皺烏帽子 specifically refers to a creased or wrinkled variant.
Compound of 皺 (しわ, 'wrinkle' or 'crease') and 烏帽子 (えぼし, 'eboshi hat'). The reading さび is an older or euphonic change from しわび, indicating a creased state.
