This tank is made of double layered lightweight jersey with Lycra Adaptiv fiber for a smoothing appearance, and still holds its shape after a day of wear. Just hang it at the end of the day and it s ready to wear again tomorrow. It s great on its own when the weather heats up and can easily be layered over with a jean jacket or light sweater. Plus, the one-shoulder style makes this tank a little more elevated for date night or other special occasions. The built in shelf bra with removable cups allows you to wear with or without a bra and still feel supported and comfortable..
