Lululemon Power Pivot tank size small in pink

Pink ribbed power pivot tank from Lululemon In great condition! Just fits a little snug on me. There is no size on this tank but it is a size small (my guess is either a size 4 or 6). For perspective, I typically wear a size 6 or 8 in Lululemon tank tops and this fits me but just is a bit too tight for my liking. Please comment with any questions 😊
