Lululemon Align Waist-Length Racerback Tank Top Blue I am not sure if it is Cerulean Blue, Poolside, or Pipe Dream Blue. Like new condition. No size tag, pit to pit approximately 13.5”, suggesting size 6 (based on other listings of the same style). When feeling nothing is everything. The lululemon Align™ collection, powered by Nulu™ fabric, is so weightless and buttery soft, all you feel is your practice. Four-way stretch Sweat-wicking Breathable Added Lycra® fibre for stretch and shape retention tight fit, waist length Contours your body Not too short, not too long, just right around the waistband Racerback shape allows for full range of movement
