Good quality & trendy color sweater
Size: Large, Color: Pure Apricot
This sweater is very soft, light and very suitable for keeping mild warm at the temperature of 20c or inside an air conditioning room. Particularly, the trendy color for 2026 in brown suede jacket, this sweater is real good matching item! I like it! 😍😍😍
