NWOT lululemon black stronger as one longline bra medium support C/D cup, size 8

NWOT lululemon black stronger as one longline bra medium support C/D cup, size 8. Perfect condition. I took the tags off and when I tried to wear it the first time it was just too tight under my bust. I need a larger size. No stains, rips, or holes. Comes from a pet and smoke free home!
