* Birka, Sweden (C9th-10th) 61 graves containing bleached or white linen shifts. Hägg categorises these into two categories, smooth and pleated [HAGG 1986]
|Discussion=In both types of shift, though far more common in the pleated shift, the neck hole was slit and fastened with a small round brooch or, more rarely, with a small penannular. The datable graves from Birka containing remnants of shifts show a trend where the smooth linen shift becomes less popular in the C10th (JBS) while the pleated shift becomes more so (HAGG 1986).The datable graves from Birka containing remnants of shifts show an increase in the number of pleated shifts in the later stages of the site (JBS) (HAGG 1986).
