Rib-knit fabric, thin knit. The color is a beautiful blue. Purchased in Fall 2023. Worn for one season. Hand-washed during the season and after the season. The neckline touches the skin, so I hand-washed it during the season as well. I haven't worn it since the following season, so I'm selling it. - Material: Rib knit - Sleeve length: Long sleeve Photo 6 shows a different color.
