This ensemble combines a tank top and a long-sleeved T-shirt, featuring two different ribbed fabrics. The tank top uses a soft and smooth cotton-rayon rib knit for a comfortable fit. The T-shirt uses a cool, needle-punched rib knit made with high-twist yarn. The needle-punching process creates a three-dimensional rib pattern, a thin, sheer fabric, and just the right amount of stretch without being too tight. While this set comes in the same color, we recommend getting multiple sets to mix and match by changing the innerwear.
