vintage impeccable fitted Long Sleeve Dress small New York Designer

This chic deep, deep navy, funnel neck dress features a sophisticated angled, welted button-up front. Late 60s -70s design but could walk the runway for Jil Sander or The Row today. Bias cut wool(?) knit. Body is lined. Excellent condition. Two tiny breaks in center back lining seam. I can’t find any holes in fabric at all. Vintage size 10 is approx a 2-4. Check measurements in photos. This designer was so coveted, he had a series of Vogue Patterns for home sewists to replicate the look. Fabulous minimalist style.
