This women’s crew neck long sleeve knit sweater is crafted from lightweight thin breathable full hollow big mesh knitted fabric. The whole-piece large hole mesh weaving creates massive air circulation gaps inside the fabric, delivering top-tier air permeability to dissipate heat quickly, solving summer sticky hot troubles and bringing cool soft unrestricted all-day wearing experience. It adopts a minimalist crew neck paired with loose drop shoulder long sleeves, featuring oversized lazy loose fit that fits petite to curvy figures comfortably. The entire top is woven with large hollow mesh openwork, presenting sheer translucent texture that brings fashionable layered aesthetic when matched with simple inner camisoles or swimsuits. Ribbed knitting on cuffs and bottom hem stabilizes the overall silhouette and resists deformation after long-term wear and washing. The ultra-light soft knit material is skin-friendly and non-bulky, no heavy burden on body. This hollow mesh knit cover-up can be worn as sun protection outerwear for seaside trips, layered over basic tees for street style, or matched with linen shorts for casual vacation looks, a must-have breathable loose layering knitwear for women’s summer wardrobe.
