Super comfortable racer back tank from Oiselle, only worn a few times. Size 4 (x small or small). From Oiselle: It's a proven fact: the more you get to know Light Lux, the more you want it on your body. The Light Lux Long Tank can easily be worn solo as a lightweight top for any kind of run or workout - or as the insanely soft layer under mid- and outer-layers. Be warned: it will also quickly become your favorite sleepwear. Racerback tank silhouette • 25.5" body length (size 4) Light Lux fabric (polyester / spandex)
