Geiger Vintage Boiled Wool Sweater Size 38 EUC (US 6?)

Geiger Vintage Boiled Wool Sweater Size 38 EUC Not your typical cardigan as it has a bit of a double breasted lower closure. Lovely buttons (pewter?) I wear a size 2 and feel it is a bit big for me even over a sweater. Size 6 maybe? Also selling a boiled wool Geiger cardigan in size 42. Chest 21” Length 21.5” Sleeves 24”
