This is a T-shaped linen or woollen garment, flaring from underarms, bust or hips to create a full skirt of ankle length. Sleeves should be full length and tight to the wrist. They are often made over long so as to cover the hand and then worn rucked back. Rolling the sleeves up the arm is considered 'Unacceptable' as this should be impossible to do with authentically tight sleeves.
The collar line should be oval or round and tight to the neck, with just enough space to get your head through. A slit can be cut at the front to form a keyhole shape and closed by ties.
For an extra layer of warmth an over-dress can be worn. These are always worn under the head covering, never over it.
A woollen over-dress is similar to a dress but has loose sleeves that end just before the wrist exposing the rucked sleeves of the dress beneath. During certain periods a version of the over-dress was worn that had a shorter skirt so as to expose the hem of the dress.
