Early Period Dress
Although there is a lot of variety, tayloring arts weren't very advanced. Most garb is a variant on the bacic [t-tunic], with interesting acessories. The length and width of the tunic changes, the colours and manner of deccoration change, etc, to make distinctive cultural dress.
T-tunics are for everyone in this period - change the fabric from loosely woven wools and linnens to finely woven wools, linnen and silks to change from rich to poor. Add lots of decorative braid or embroidery to indicate wealth. Harder to obtain colours like purple, blue and green indicate wealth, while yellow, duller reds and oranges, boring browns etc were colours for the poorer. Black occured, but was rarely colourfast, a colour for the rich, but most would prefer a garment that still looked good (rather than faded) in a months time. In later periods, black becomes more common.
Girls wear longer tunics (at least ankle length), while guys wear shorter tunics (from just above height to ankle length, the longer ones sometime slit up the side for free movement). Guys might wear braes (loose pants) under their tunics, or hose (sometimes hose would have soles sewn to them, rather than wear shoes). Vikings wore leg wrappings to keep their braes out of the way.
Further east, out of europe, fashions change a bit, but in byantium, they were also wearing their own kind of t-tunic by about 1000.
