Vintage '60s two piece sweater set

Society size 16💥Definitely from MY🏵️Ahma/Tutu/Mama closet. '60s era sweater set-wool blend, long sleeve sweater and matching pants. Been in storage for decades, I've never worn it. It's also a garment I had no idea how to clean or care for- close up of fabric. It's very heavy and I imagine very warm.
