Lululemon built in bra tank.

I couldn't find the original tank on Lululemons site. It is one of the Free to Be bra's but I'm unsure of exactly which one. I bought this second hand so I don't have the original details. It is in excellent condition, with originally padding still in it. The back drapes down so it is an open back. The stripes are a grey/cream, and the tank itself is a black/grey Heather. The bra is black.
