Reconstructing a Viking Hanging Dress from Haithabu
From study of archaeological material and artistic representations, the characteristic Scandinavian female attire is understood to be a pinafore dress with a straight top margin across the breast, suspended from shoulder straps which were fastened with a pair of large oval brooches (Fig. 1):

Description of find
Two pieces, probably of the same garment (Fig. 2), recycled as rags and discarded in the harbour at Haithabu (Hedeby). The largest piece (14A) is trapezoidal, 30cm high and broadening from 16 to 23cm, where the lower edge is torn away. The top margin, which is made from the selvedge of the fabric, is turned under once and fixed with an elaborate hemming seam. The sides - one is cut straight and perpendicular to the selvedge, the other somewhat curved - must have been seam positions, as they still bear traces of stitch holes. Parallel to the straight edge, and starting about 7cm from the top, a simple dart has been formed using running stitch, and a braided cord has been applied to the ridge thus formed using whip stitch. About 15cm below the top edge, where the dart is deepest, the fabric is noticeably worn and felted. Other wear is apparent near the top margin.

Technical description of weave - Wool, fabric is ~1mm thick. Finely woven tabby (1/1, Z/S), 15(warp) x 8-10 (weft) threads per cm. Simple unreinforced selvedge. Originally artificially coloured, but now brown.
Upper margin seam (Fig. 3) - A selvedge is turned under about 1cm. It is hemmed down with alternating backstitch using a 2-ply woolen thread (z-spun S-plied). Stitch length is 7-8mm and interval is 3-5mm.
Side seams - Insufficient remains to show the type of seam, but the stitch interval is 5-6mm. At Haithabu, construction seams are most often overcast using whipstiches.
Dart seam and applied cord (Fig. 4) - The dart is formed by pinching a fold from 2 to 5mm deep and securing it with running stitch using a single z-spun woolen thread. Stitch length is 3mm and interval is 5-6mm.
H14A/B is probably the side panel of a hanging dress. It was a fitted, tailored garment, as shown here by use of a shaped seam and a dart. To prevent the dress slipping, the upper edge fitted tightly around the chest. Ingenious use of a selvedge made this margin firm, and the sewing technique with which it was hemmed acted like modern zig-zag stitch, able to stretch without breaking.

B= outline of right brooch; E= matching marks from brooch in the fabric; H= hemmed upper margin of worsted wool fabric; L= linen loops around iron brooch pin, woolen threads adhere to the lower set; S?= possible position of a side seam.
From this remnant it can be determined that the front brooch loops were set 20-22cm apart, and the fabric extended at least 4-5cm further to the sides. In another Birka grave, Bj464, the side seam was actually preserved in this position (Fig. 7):

From these two Birka finds an overall width of about 30cm for the front panel can be inferred.
The basic principle of early medieval tailoring was to piece the garment out of simple rectangular and triangular parts, in such a way as to minimise or even eliminate wasteage of valuable material.
Using all of the abovementioned remains as a guide, a pattern based on four fairly equal rectangles is suggested (Fig. 8):
When the side panel is placed with curved edge frontwards, the decorative cord marks a line down the side of the body.
There is now no trace of the loops of the Haithabu dress. Hägg suggests that the worn-out spot near the upper edge is where a loop was attached, but in our reconstruction it seems more likely to be where the arm and body rubbed together.
