Lululemon long sleeves

The black and white one I bought from the store and is in perfect condition, it’s a size 12 though I tore out the rip tag. The black one I got on here and it was advertised as a size 10/12. The black one is in good condition with some pilling along the seems. The black one is lightweight cotton while the black and white one is more of a sweat wicking material. Would keep but the cutouts in the back always make me cold.
