VINTAGE Aljean plaid tartan blazer skirt set

Aljean of Canada VINTAGE pleated skirt and blazer set. I’m excellent condition. Got it from a family member but it doesn’t fit me correctly. Marked as a size 12 Canada so it would be about a size 10 in US. I’m usually a size 6 and the skirt fits well, not too loose and not too tight. The jacket is large on me as my upper half is petite. The blazer has shoulder pads. The set is from around the late 1970s, I couldn’t find an exact match online so I’m going off of what my family member said.
