LULULEMON POWER Y TANK BLUE great condition size: not gonna lie i’m not sure…. it is either a 4 or a 6. i’m in between and have bought both in the past and then I cut out the tag long ago…. so, if i had to guess i’m going to say 6 but again, not sure….. if you fit in either size 4 OR 6 then this might be perfect for you!!! 😅🤪😅🤪😅🤪
