Nice quality sweater, well made and soft.
Size: Large, Color: Pure Beige
I love this sweater - but I bought it just in time for summer, so it won't get much use until fall! It fits great, it is really soft and the overall quality is quite good. I plan to buy another one in another color as well.

Nice casual looking sweater
Size: Small, Color: Pure Black
I purchased the black/cream inset sweater in a small. I usually wear a small. I fits loose, but NOT baggy. I like the loose fit. The sweater feels so soft. Nice looking sweater. Very happy with the sweater, but could have ordered a medium for a boxier fit.

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! 😍😍😍
