Did vikings wear plaid

Answer 1

Vikings wore clothing made from varying qualities wool or linen and if they were rich, they may have silk.

While we have hard times distinguishing what Viking men wore during that period since much of it decayed. At a pre-viking dig they found a man who was buried in one outfit containing not only multicoloured plaid pants but also a plaid cloak of a different design and three different kinds of intricately patterned tablet-weaving.

So it's theoretically plausible that Viking had them but it's not a certainty
