Vintage matching plaid set

I'm so in love with this set, vintage tan plaid button down collared short sleeve top with a matching skirt with a raw hem that I cut myself, Measurements in pictures. Shown on a size small 5'6 model. I really don't want to give this up but I don't think id wear it enough. Vintage set plaid set button down skirt Not asos, it's vintage. Just tagged for exposure. My estimate is this is from the early 90s by the tag! 🎀
