Vintage 60s Angohmere Luisa Spagnoli Perugia Italy Cashmere Angora Coordinate Set - Cardigan and Short Sleeve Sweater
No fabric content tag but based on name, I assume angora and cashmere are in the blend.
No size tag - may fit modern XS or S - compare measurements:
The CARDIGAN SWEATER: 19" across underarm to underarm so bust less than 38" to allow buttons to remain relaxed when closed, 18" across bottom so waist less than 36", 22" long, arm holes measure 9" across so 18" around upper arm, sleeve is 17" from shoulder, 15. 5" shoulder. Model is 5'8" XS with 32" bust
The SHORT SLEEVE: 36-38" bust, 21" long, 15" shoulders
Nice condition. To my eye the collar of the short sleeve is somewhat yellowed. Mild wear (some pills)

This item is sold from an excellent, highly rated vintage boutique.
