Vintage McGreggor Sportswear plaid pants

I bought these on Etsy and they don’t fit me, so hoping to resell here. Sizing: Waist 30” Inseam 30” Length from waist to hem 40” However, I’m a size 8 and I can barely zip these up. These are more of a size 6. There is no sizing info on the tag. Great pants, just don’t fit me.
